+
+## Flake Outputs
+
+`flake.nix` is the entry point that defines all outputs:
+
+### Packages
+
+```nix
+packages = forAllSystems (system: let
+  pkgs = pkgsFor system;
+in
+  import ./pkgs {inherit pkgs;});
+```
+
+- Built for all supported systems
+- Uses `callPackage` pattern for lazy evaluation
+- Available via `nix build .#<package-name>`
+
+### Overlays
+
+```nix
+overlays = {
+  # Default overlay: adds all custom packages
+  default = final: prev: import ./pkgs {pkgs = final;};
+
+  # Additions overlay: same as default
+  additions = final: prev: import ./pkgs {pkgs = final;};
+
+  # Modifications overlay: modifies existing nixpkgs packages
+  modifications = final: prev: import ./overlays/mods {inherit prev;};
+};
+```
+
+- `default`: Adds all custom packages to nixpkgs
+- `additions`: Individual package additions
+- `modifications`: Overrides existing packages
+
+### NixOS Modules
+
+```nix
+nixosModules = {
+  default = ./modules/nixos;  # Import all modules
+  ports = ./modules/nixos/ports.nix;  # Specific module
+  mem0 = ./modules/nixos/mem0.nix;
+};
+```
+
+- System-level configuration modules
+- Use `m3ta.*` namespace
+- Can import all modules or individual ones
+
+### Home Manager Modules
+
+```nix
+homeManagerModules = {
+  default = import ./modules/home-manager;
+  ports = import ./modules/home-manager/ports.nix;
+  zellij-ps = import ./modules/home-manager/zellij-ps.nix;
+};
+```
+
+- User-level configuration modules
+- Categorized by function (cli, coding)
+- Use `m3ta.*` namespace
+
+### Library Functions
+
+```nix
+lib = forAllSystems (system: let
+  pkgs = pkgsFor system;
+in
+  import ./lib {lib = pkgs.lib;});
+```
+
+- Helper functions for configuration
+- Port management utilities
+- Can be used in your configurations
+
+### Development Shells
+
+```nix
+devShells = forAllSystems (system: let
+  pkgs = pkgsFor system;
+in
+  import ./shells {inherit pkgs;});
+```
+
+- Pre-configured development environments
+- Available: `default`, `python`, `devops`
+- Usage: `nix develop .#<shell-name>`
+
+### Templates
+
+```nix
+templates = {
+  package = {
+    path = ./templates/package;
+    description = "Template for a new package";
+  };
+  nixos-module = {
+    path = ./templates/nixos-module;
+    description = "Template for a new NixOS module";
+  };
+  home-manager-module = {
+    path = ./templates/home-manager-module;
+    description = "Template for a new Home Manager module";
+  };
+};
+```
+
+- Boilerplate for quick start
+- Usage: `nix flake init -t .#template-name`
+
+## Package Organization
+
+### Registry Pattern
+
+`pkgs/default.nix` acts as a central registry:
+
+```nix
+{
+  inherit (pkgs) callPackage;
+} rec {
+  code2prompt = callPackage ./code2prompt {};
+  hyprpaper-random = callPackage ./hyprpaper-random {};
+  mem0 = callPackage ./mem0 {};
+  # ...
+}
+```
+
+**Benefits**:
+- Lazy evaluation: only builds requested packages
+- Consistent interface: all packages use `callPackage`
+- Easy discovery: one file lists all packages
+
+### Package Structure
+
+Each package lives in its own directory:
+
+```
+pkgs/your-package/
+├── default.nix    # Package definition
+├── source.py      # Optional: source files
+└── README.md      # Optional: package documentation
+```
+
+**Conventions**:
+- Directory name matches registry attribute
+- Use `callPackage` for dependencies
+- Always include `meta` with all fields
+
+### Common Package Patterns
+
+#### Rust Packages
+
+```nix
+rustPlatform.buildRustPackage rec {
+  pname = "myapp";
+  version = "1.0.0";
+  src = fetchFromGitHub { ... };
+  cargoLock.lockFile = src + "/Cargo.lock";
+  # ...
+}
+```
+
+#### Python Packages
+
+```nix
+python3.pkgs.buildPythonPackage rec {
+  pname = "mypythonapp";
+  version = "1.0.0";
+  src = fetchFromGitHub { ... };
+  dependencies = with python3.pkgs; [requests click];
+  # ...
+}
+```
+
+#### Shell Scripts
+
+```nix
+writeShellScriptBin "myscript" ''
+  #!/usr/bin/env bash
+  echo "Hello World"
+''
+```
+
+#### AppImage
+
+```nix
+appimageTools.wrapType2 rec {
+  name = "myapp";
+  src = fetchurl { ... };
+  # ...
+}
+```
+
+## Module Organization
+
+### NixOS Modules
+
+Located in `modules/nixos/`:
+
+```
+modules/nixos/
+├── default.nix    # Imports all modules
+├── ports.nix      # Port management
+├── mem0.nx        # Individual module
+```
+
+**Pattern**:
+
+```nix
+{config, lib, pkgs, ...}:
+with lib; let
+  cfg = config.m3ta.myModule;
+in {
+  options.m3ta.myModule = {
+    enable = mkEnableOption "description";
+    # ... options
+  };
+
+  config = mkIf cfg.enable {
+    # ... configuration
+  };
+}
+```
+
+### Home Manager Modules
+
+Located in `modules/home-manager/` with categories:
+
+```
+modules/home-manager/
+├── default.nix      # Imports all modules
+├── ports.nix       # Port management
+├── cli/
+│   ├── default.nix # Aggregates CLI modules
+│   └── zellij-ps.nix
+└── coding/
+    ├── default.nix # Aggregates coding modules
+    └── editors.nix
+```
+
+**Categories**:
+- `cli/`: Command-line tools and utilities
+- `coding/`: Development tools and editors
+
+**Pattern** (same as NixOS):
+
+```nix
+{config, lib, pkgs, ...}:
+with lib; let
+  cfg = config.m3ta.coding.editors;
+in {
+  options.m3ta.coding.editors = {
+    enable = mkEnableOption "editor configuration";
+    # ... options
+  };
+
+  config = mkIf cfg.enable {
+    # ... configuration
+  };
+}
+```
+
+## Library Functions
+
+Located in `lib/`:
+
+```nix
+{lib}: {
+  # Port management utilities
+  ports = import ./ports.nix {inherit lib;};
+}
+```
+
+### Port Management
+
+Centralized port management across hosts:
+
+```nix
+# Usage in configuration
+portHelpers = inputs.m3ta-nixpkgs.lib.${system}.ports.mkPortHelpers myPorts;
+
+# Get port with host override
+services.nginx.port = portHelpers.getPort "nginx" "laptop";
+
+# Get all ports for host
+allLaptopPorts = portHelpers.getHostPorts "laptop";
+```
+
+**Benefits**:
+- Single source of truth for ports
+- Host-specific overrides
+- Avoid port conflicts
+
+## Naming Conventions
+
+| Context | Convention | Example |
+|---------|------------|---------|
+| Packages | `lowercase-hyphen` | `hyprpaper-random` |
+| Variables | `camelCase` | `portHelpers` |
+| Module options | `m3ta.*` | `m3ta.ports.enable` |
+| Files | `lowercase-hyphen` | `my-module.nix` |
+| Directories | `lowercase-hyphen` | `cli/`, `coding/` |
+
+## Code Patterns
+
+### Module Options
+
+Always use `mkEnableOption` for enable flags:
+
+```nix
+options.m3ta.myModule = {
+  enable = mkEnableOption "description";
+};
+```
+
+### Conditional Configuration
+
+Use `mkIf` for conditional config:
+
+```nix
+config = mkIf cfg.enable {
+  # Only applied when cfg.enable is true
+};
+```
+
+### Multiple Conditions
+
+Use `mkMerge` for multiple conditions:
+
+```nix
+config = mkMerge [
+  (mkIf cfg.feature1.enable { ... })
+  (mkIf cfg.feature2.enable { ... })
+];
+```
+
+### Imports
+
+Multi-line, trailing commas:
+
+```nix
+{
+  lib,
+  stdenv,
+  fetchFromGitHub,
+}:
+```
+
+### Meta Fields
+
+Always include all fields:
+
+```nix
+meta = with lib; {
+  description = "...";
+  homepage = "...";
+  license = licenses.mit;
+  platforms = platforms.linux;
+  mainProgram = "program-name";
+};
+```
+
+## Design Decisions
+
+### Flakes-Only
+
+**Decision**: Use flakes exclusively, no channels.
+
+**Rationale**:
+- Reproducible builds
+- Explicit dependencies
+- Better integration with modern Nix tooling
+
+### CallPackage Pattern
+
+**Decision**: Use `callPackage` for all packages.
+
+**Rationale**:
+- Lazy evaluation
+- Clear dependency graph
+- Consistent interface
+
+### Module Categorization
+
+**Decision**: Categorize Home Manager modules by function.
+
+**Rationale**:
+- Easier to find related modules
+- Logical organization
+- Follows user mental model
+
+### Port Management
+
+**Decision**: Centralized port management with host overrides.
+
+**Rationale**:
+- Avoid port conflicts
+- Easy to manage multiple hosts
+- Single source of truth
+
+### Namespace Convention
+
+**Decision**: Use `m3ta.*` namespace for all modules.
+
+**Rationale**:
+- Avoid conflicts
+- Clear attribution
+- Easy to discover
+
+## Supported Systems
+
+- `x86_64-linux` - Primary development target
+- `aarch64-linux` - ARM Linux
+- `x86_64-darwin` - macOS Intel
+- `aarch64-darwin` - macOS Apple Silicon
+
+**Note**: Some packages may be Linux-only (check `meta.platforms`).

+
+## Troubleshooting
+
+### Hash Errors
+
+When building packages, you may encounter hash errors:
+
+```
+got: sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=
+expected: sha256-BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB=
+```
+
+**Solution**: Copy the `got` hash and update the package:
+
+```nix
+src = fetchFromGitHub {
+  # ...
+  hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";  # Use actual hash
+};
+```
+
+### Dependency Not Found
+
+If a package isn't found, check:
+1. Package registered in `pkgs/default.nix`
+2. Overlay applied in your configuration
+3. System matches supported platform
+
+### Linting Errors
+
+```bash
+# Fix statix issues manually or use auto-fix where available
+statix fix .
+
+# Review deadnix suggestions
+deadnix -e .
+```
+
+## Getting Help
+
+- Check existing packages and modules for patterns
+- Read [Architecture](./ARCHITECTURE.md) for design decisions
+- Review [Code Patterns](./reference/patterns.md) for conventions
+- Open an issue for questions
+
+## Anti-Patterns
+
+| Don't | Do Instead |
+|-------|------------|
+| `lib.fakeHash` in commits | Get real hash: `nix build`, copy from error |
+| Flat module files | Organize by category (`cli/`, `coding/`) |
+| Hardcode ports | Use `m3ta.ports` module |
+| Skip meta fields | Include all: description, homepage, license, platforms, mainProgram |
+| `with pkgs;` in modules | Explicit `pkgs.package` or `with pkgs; [ ... ]` in lists only |
+| Suppress type errors | Fix underlying type issues |
+| Delete tests to "pass" | Fix failing tests |
+
+## Code Review Checklist
+
+- [ ] Follows naming conventions
+- [ ] Properly formatted (`nix fmt`)
+- [ ] Passes linting (`statix`, `deadnix`)
+- [ ] Has complete `meta` fields (packages)
+- [ ] Documentation updated if needed
+- [ ] No dead code
+- [ ] No obvious bugs or issues
+- [ ] Appropriate for scope
+
+## Release Process
+
+This is a personal repository, but semantic versioning is followed for tags:
+
+1. Update versions as needed
+2. Update changelog
+3. Tag release
+4. Push tags
+
+```bash
+git tag -a v1.0.0 -m "Release v1.0.0"
+git push origin v1.0.0
+```

+      inherit system;
+      overlays = [m3ta-nixpkgs.overlays.default];
+    };
+  in {
+    homeConfigurations.yourusername = home-manager.lib.homeManagerConfiguration {
+      inherit pkgs;
+      extraSpecialArgs = {inherit inputs;};
+      modules = [
+        m3ta-nixpkgs.homeManagerModules.default
+        {
+          home.username = "yourusername";
+          home.homeDirectory = "/home/yourusername";
+          home.packages = with pkgs; [
+            code2prompt
+            zellij-ps
+          ];
+          programs.home-manager.enable = true;
+        }
+      ];
+    };
+  };
+}
+```
+
+## Using Packages Without Configuration
+
+You can build and run packages directly without adding to your configuration:
+
+```bash
+# Build a package
+nix build git+https://code.m3ta.dev/m3tam3re/nixpkgs#code2prompt
+
+# Run a package
+nix run git+https://code.m3ta.dev/m3tam3re/nixpkgs#zellij-ps
+
+# List all available packages
+nix flake show git+https://code.m3ta.dev/m3tam3re/nixpkgs
+```
+
+## Common Use Cases
+
+### Use a Package System-Wide
+
+```nix
+# In configuration.nix
+{pkgs, ...}: {
+  environment.systemPackages = with pkgs; [
+    code2prompt      # From m3ta-nixpkgs
+    git             # From nixpkgs
+  ];
+}
+```
+
+### Use a Package for Your User Only
+
+```nix
+# In home.nix
+{pkgs, ...}: {
+  home.packages = with pkgs; [
+    launch-webapp
+    zellij-ps
+  ];
+}
+```
+
+### Use a NixOS Module
+
+```nix
+{config, ...}: {
+  imports = [
+    # Or import the default which includes all modules
+  ];
+
+  # Enable mem0 service
+  m3ta.mem0 = {
+    enable = true;
+    port = 8000;
+    llm = {
+      provider = "openai";
+      apiKeyFile = "/run/secrets/openai-api-key";
+    };
+  };
+}
+```
+
+### Use Port Management
+
+```nix
+{config, ...}: {
+  m3ta.ports = {
+    enable = true;
+    definitions = {
+      nginx = 80;
+      grafana = 3000;
+    };
+    hostOverrides.laptop = {
+      nginx = 8080;  # Override on laptop
+    };
+    currentHost = config.networking.hostName;
+  };
+
+  services.nginx = {
+    enable = true;
+    httpConfig = ''
+      server {
+        listen ${toString (config.m3ta.ports.get "nginx")};
+      }
+    '';
+  };
+}
+```
+
+## Available Packages
+
+| Package            | Description                           |
+| ------------------ | ------------------------------------- |
+| `code2prompt`      | Convert code to prompts               |
+| `hyprpaper-random` | Random wallpaper setter for Hyprpaper |
+| `launch-webapp`    | Launch web applications               |
+| `mem0`             | AI memory assistant with vector storage |
+| `msty-studio`      | Msty Studio application               |
+| `pomodoro-timer`   | Pomodoro timer utility                |
+| `tuxedo-backlight` | Backlight control for Tuxedo laptops  |
+| `zellij-ps`        | Project switcher for Zellij           |
+
+## Essential Commands
+
+```bash
+# Validate your configuration
+nix flake check
+
+# Format Nix files
+nix fmt
+
+# Apply NixOS configuration
+sudo nixos-rebuild switch
+
+# Apply Home Manager configuration
+home-manager switch
+
+# Enter development shell
+nix develop .#python  # Python shell
+nix develop .#devops  # DevOps shell
+
+# List all outputs
+nix flake show
+```
+
+## Development Workflow
+
+```bash
+# Clone repository
+git clone https://code.m3ta.dev/m3tam3re/nixpkgs.git
+cd nixpkgs
+
+# Create a new package
+nix flake init -t .#package
+
+# Test package build
+nix build .#your-package
+
+# Run linting (in dev shell)
+nix develop
+statix check .
+deadnix .
+
+# Format before commit
+nix fmt
+```
+
+## Troubleshooting
+
+### Package Not Found
+
+Make sure you applied the overlay:
+
+```nix
+nixpkgs.overlays = [m3ta-nixpkgs.overlays.default];
+```
+
+Or reference directly:
+
+```nix
+inputs.m3ta-nixpkgs.packages.${pkgs.system}.package-name
+```
+
+### Module Not Found
+
+Make sure you imported the module:
+
+```nix
+imports = [
+  m3ta-nixpkgs.nixosModules.default
+  # or specific module:
+  m3ta-nixpkgs.nixosModules.mem0
+];
+```
+
+### Hash Mismatch
+
+If you're developing and get a hash error, rebuild to get the real hash:
+
+```bash
+nix build .#your-package
+# Copy hash from error and update package
+```

+
+## Key Concepts
+
+### Flakes-Only Approach
+
+This repository uses modern Nix flakes exclusively. No channels or `nix-channel` commands are needed. All dependencies are declaratively specified in `flake.nix`.
+
+### Namespace Convention
+
+All modules use the `m3ta.*` namespace:
+
+- `m3ta.ports.*` - Port management
+- `m3ta.mem0.*` - Mem0 service configuration
+- `m3ta.*.enable` - Enable/disable modules
+
+### Port Management
+
+Centralized port management across hosts using the `m3ta.ports` module:
+
+```nix
+m3ta.ports = {
+  enable = true;
+  definitions = { mem0 = 8000; };
+  hostOverrides.laptop = { mem0 = 8080; };
+  currentHost = "laptop";
+};
+```
+
+## Supported Systems
+
+- `x86_64-linux` - Primary
+- `aarch64-linux` - ARM Linux
+- `x86_64-darwin` - macOS (Intel)
+- `aarch64-darwin` - macOS (Apple Silicon)
+
+## Quick Commands

+# Adding Packages Guide
+
+How to add new packages to m3ta-nixpkgs.
+
+## Overview
+
+Packages in m3ta-nixpkgs are organized using a `callPackage` registry pattern. Each package lives in its own directory and is registered centrally.
+
+## Quick Start
+
+### Using Templates
+
+Use the package template for quick setup:
+
+```bash
+nix flake init -t .#package my-new-package
+```
+
+This creates a template structure in `templates/package/` that you can copy.
+
+### Manual Setup
+
+1. Create directory: `pkgs/your-package/`
+2. Write `default.nix` with package definition
+3. Register in `pkgs/default.nix`
+
+## Package Structure
+
+```
+pkgs/your-package/
+├── default.nix       # Package definition (required)
+├── source.py         # Optional: additional source files
+├── wrapper.sh        # Optional: wrapper scripts
+└── README.md         # Optional: package documentation
+```
+
+## Common Patterns
+
+### Rust Package
+
+```nix
+{
+  lib,
+  rustPlatform,
+  fetchFromGitHub,
+}:
+rustPlatform.buildRustPackage rec {
+  pname = "my-rust-app";
+  version = "1.0.0";
+
+  src = fetchFromGitHub {
+    owner = "author";
+    repo = "my-rust-app";
+    rev = "v${version}";
+    hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
+  };
+
+  cargoLock.lockFile = src + "/Cargo.lock";
+
+  buildInputs = [openssl];
+
+  nativeBuildInputs = [pkg-config];
+
+  meta = with lib; {
+    description = "My Rust application";
+    homepage = "https://github.com/author/my-rust-app";
+    license = licenses.mit;
+    platforms = platforms.linux;
+    mainProgram = "my-rust-app";
+  };
+}
+```
+
+### Python Package
+
+```nix
+{
+  lib,
+  python3,
+  fetchFromGitHub,
+}:
+python3.pkgs.buildPythonPackage rec {
+  pname = "my-python-app";
+  version = "1.0.0";
+  pyproject = true;
+
+  src = fetchFromGitHub {
+    owner = "author";
+    repo = "my-python-app";
+    rev = "v${version}";
+    hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
+  };
+
+  build-system = with python3.pkgs; [setuptools];
+
+  dependencies = with python3.pkgs; [
+    requests
+    click
+  ];
+
+  optional-dependencies = with python3.pkgs; {
+    extras = [pyyaml];
+  };
+
+  doCheck = true;
+
+  pythonImportsCheck = ["myapp"];
+
+  meta = with lib; {
+    description = "My Python application";
+    homepage = "https://github.com/author/my-python-app";
+    license = licenses.mit;
+    platforms = platforms.linux;
+    mainProgram = "my-app";
+  };
+}
+```
+
+### Shell Script Package
+
+```nix
+{
+  lib,
+  writeShellScriptBin,
+}:
+writeShellScriptBin "my-script" ''
+  #!/usr/bin/env bash
+  set -euo pipefail
+
+  echo "Hello from my script!"
+
+  # Your script logic here
+''
+
+# If you need to add dependencies
+{
+  lib,
+  writeShellApplication,
+  bash,
+  curl,
+}:
+writeShellApplication {
+  name = "my-script";
+  runtimeInputs = [bash curl];
+  text = ''
+    #!/usr/bin/env bash
+    set -euo pipefail
+
+    curl -s https://example.com
+  '';
+}
+```
+
+### AppImage Package
+
+```nix
+{
+  lib,
+  appimageTools,
+  fetchurl,
+}:
+appimageTools.wrapType2 rec {
+  name = "my-app";
+  version = "1.0.0";
+
+  src = fetchurl {
+    url = "https://github.com/author/my-app/releases/download/v${version}/My-App-${version}.AppImage";
+    hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
+  };
+
+  meta = with lib; {
+    description = "My AppImage application";
+    homepage = "https://github.com/author/my-app";
+    license = licenses.unfree;
+    platforms = platforms.linux;
+    mainProgram = name;
+  };
+}
+```
+
+### Custom Source with Patch
+
+```nix
+{
+  lib,
+  stdenv,
+  fetchFromGitHub,
+  fetchpatch,
+  buildGoModule,
+}:
+buildGoModule rec {
+  pname = "my-go-app";
+  version = "1.0.0";
+
+  src = fetchFromGitHub {
+    owner = "author";
+    repo = "my-go-app";
+    rev = "v${version}";
+    hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
+  };
+
+  patches = [
+    # Add local patch
+    ./fix-build.patch
+
+    # Add patch from URL
+    (fetchpatch {
+      url = "https://github.com/author/my-app/pull/123.patch";
+      hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
+    })
+  ];
+
+  vendorHash = "sha256-BBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBBB=";
+
+  meta = with lib; {
+    description = "My Go application";
+    homepage = "https://github.com/author/my-go-app";
+    license = licenses.mit;
+    platforms = platforms.linux;
+    mainProgram = "my-app";
+  };
+}
+```
+
+### Package with Custom Installation
+
+```nix
+{
+  lib,
+  stdenv,
+  fetchFromGitHub,
+  makeWrapper,
+}:
+stdenv.mkDerivation rec {
+  pname = "my-app";
+  version = "1.0.0";
+
+  src = fetchFromGitHub {
+    owner = "author";
+    repo = "my-app";
+    rev = "v${version}";
+    hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";
+  };
+
+  nativeBuildInputs = [makeWrapper];
+
+  buildPhase = ''
+    make build
+  '';
+
+  installPhase = ''
+    install -Dm755 my-app $out/bin/my-app
+
+    # Wrap with runtime dependencies
+    wrapProgram $out/bin/my-app \
+      --prefix PATH : ${lib.makeBinPath [some-dep]}
+  '';
+
+  meta = with lib; {
+    description = "My custom application";
+    homepage = "https://github.com/author/my-app";
+    license = licenses.mit;
+    platforms = platforms.linux;
+    mainProgram = "my-app";
+  };
+}
+```
+
+## Registration
+
+### Register in `pkgs/default.nix`
+
+Add your package to the registry:
+
+```nix
+{
+  inherit (pkgs) callPackage;
+} rec {
+  # Existing packages
+  code2prompt = callPackage ./code2prompt {};
+  zellij-ps = callPackage ./zellij-ps {};
+
+  # Your new package
+  my-new-package = callPackage ./my-new-package {};
+}
+```
+
+### With Custom Arguments
+
+If your package needs custom arguments:
+
+```nix
+# pkgs/default.nix
+{
+  inherit (pkgs) callPackage;
+} rec {
+  my-new-package = callPackage ./my-new-package {
+    customArg = "value";
+  };
+}
+
+# pkgs/my-new-package/default.nix
+{
+  lib,
+  stdenv,
+  fetchurl,
+  customArg,  # This will be passed from the registry
+}:
+stdenv.mkDerivation {
+  # ...
+}
+```
+
+## Getting Hashes
+
+### Using `lib.fakeHash`
+
+During development, use `lib.fakeHash` to get the real hash:
+
+```nix
+src = fetchFromGitHub {
+  owner = "author";
+  repo = "my-app";
+  rev = "v${version}";
+  hash = lib.fakeHash;  # Temporary placeholder
+};
+```
+
+Build the package:
+
+```bash
+nix build .#my-new-package
+```
+
+Copy the actual hash from the error message and update the package:
+
+```nix
+hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";  # Real hash
+```
+
+**Important**: Never commit `lib.fakeHash` to the repository.
+
+## Testing
+
+### Build Package
+
+```bash
+nix build .#my-new-package
+```
+
+### Test Execution
+
+```bash
+nix run .#my-new-package -- --help
+```
+
+### Run in Shell
+
+```bash
+nix shell .#my-new-package
+my-new-app --version
+```
+
+### Linting
+
+```bash
+nix develop
+statix check pkgs/my-new-package/
+```
+
+## Best Practices
+
+### Meta Fields
+
+Always include complete `meta` information:
+
+```nix
+meta = with lib; {
+  description = "Short one-line description";
+  longDescription = ''
+    Longer description explaining what the package does,
+    its features, and use cases.
+  '';
+  homepage = "https://github.com/author/repo";
+  changelog = "https://github.com/author/repo/releases/tag/v${version}";
+  license = licenses.mit;
+  platforms = platforms.linux;
+  mainProgram = "program-name";
+};
+```
+
+### Dependencies
+
+Explicitly declare all dependencies:
+
+```nix
+{
+  lib,
+  stdenv,
+  fetchFromGitHub,
+  # Runtime dependencies
+  openssl,
+  curl,
+  # Native build dependencies
+  pkg-config,
+  cmake,
+}:
+```
+
+### Versioning
+
+Use `rec` to reference `version` in multiple places:
+
+```nix
+rec {
+  pname = "my-app";
+  version = "1.0.0";
+
+  src = fetchFromGitHub {
+    rev = "v${version}";
+    # ...
+  };
+}
+```
+
+### Platform Restrictions
+
+If package is platform-specific:
+
+```nix
+meta = with lib; {
+  # Linux only
+  platforms = platforms.linux;
+
+  # Or specific platforms
+  platforms = ["x86_64-linux" "aarch64-linux"];
+
+  # Or exclude platforms
+  broken = stdenv.isDarwin;
+};
+```
+
+## Troubleshooting
+
+### Hash Mismatch
+
+Error: `got: sha256-AAAAAAAA... expected: sha256-BBBBBB...`
+
+Solution: Copy `got` hash and update package definition.
+
+### Dependency Not Found
+
+Error: `error: undefined variable 'somedep'`
+
+Solution: Add dependency to function arguments and build inputs:
+
+```nix
+{
+  lib,
+  somedep,  # Add here
+}:
+stdenv.mkDerivation {
+  buildInputs = [somedep];  # Add here
+}
+```
+
+### Import Check Failure
+
+Error: `error: Python module 'mymodule' not found`
+
+Solution: Disable or fix imports check:
+
+```nix
+pythonImportsCheck = ["mymodule"];  # Check this is correct
+# Or if importing creates side effects:
+pythonImportsCheck = [];
+```
+

+
+# Check if dependencies are satisfied
+nix path-info .#my-package --references
+```
+
+## Continuous Integration
+
+### Pre-Commit Hook
+
+Create `.git/hooks/pre-commit`:
+
+```bash
+#!/usr/bin/env bash
+set -euo pipefail
+
+# Format code
+nix fmt
+
+# Lint
+statix check .
+deadnix .
+
+# Validate
+nix flake check
+
+# Test build
+nix build .#your-package
+```
+
+Make executable:
+
+```bash
+chmod +x .git/hooks/pre-commit
+```
+
+### Pre-Push Hook
+
+Create `.git/hooks/pre-push`:
+
+```bash
+#!/usr/bin/env bash
+set -euo pipefail
+
+# Validate flake
+nix flake check
+
+# Run tests if they exist
+# make test
+```
+
+## Debugging
+
+### Build Failures
+
+#### Hash Mismatch
+
+Error: `got: sha256-AAAAAAAA... expected: sha256-BBBBBB...`
+
+Solution: Copy the `got` hash and update package:
+
+```nix
+src = fetchFromGitHub {
+  hash = "sha256-AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA=";  # Use actual hash
+};
+```
+
+#### Dependency Not Found
+
+Error: `error: undefined variable 'somelib'`
+
+Solution: Check function arguments:
+
+```nix
+{
+  lib,
+  stdenv,
+  fetchFromGitHub,
+  somelib,  # Add this if missing
+}:
+```
+
+#### Build Failed
+
+Error: `builder for '/nix/store/...' failed`
+
+Solution:
+
+```bash
+# Build with verbose output
+nix build .#my-package -v --show-trace
+
+# Check build logs
+nix log .#my-package
+
+# Enter build environment for debugging
+nix shell -f .#my-package .bashInteractive
+```
+
+### Runtime Failures
+
+#### Package Not Executable
+
+Error: `error: operation not permitted`
+
+Solution: Check `mainProgram` in meta:
+
+```nix
+meta = with lib; {
+  mainProgram = "my-app";  # Must match executable name
+};
+```
+
+#### Library Not Found
+
+Error: `error while loading shared libraries: libfoo.so`
+
+Solution: Add to build inputs:
+
+```nix
+buildInputs = [someLib];
+```
+
+### Configuration Failures
+
+#### Option Not Found
+
+Error: `error: The option 'm3ta.mymodule' does not exist`
+
+Solution: Import the module:
+
+```nix
+imports = [
+  m3ta-nixpkgs.nixosModules.default
+];
+```

+# Getting Started Guide
+
+Initial setup and basic usage of m3ta-nixpkgs.
+
+## Installation
+
+### Prerequisites
+
+Make sure you have Nix installed with flakes enabled:
+
+```bash
+# Check Nix version (need 2.4+)
+nix --version
+
+# Enable flakes (in /etc/nixos/configuration.nix)
+nix.settings.experimental-features = ["nix-command" "flakes"]
+
+# Rebuild NixOS
+sudo nixos-rebuild switch
+```
+
+### Adding to Your Flake
+
+#### Option 1: NixOS Configuration
+
+Add to your `flake.nix`:
+
+```nix
+{
+  description = "My NixOS configuration";
+
+  inputs = {
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
+    home-manager.url = "github:nix-community/home-manager";
+
+    m3ta-nixpkgs = {
+      url = "git+https://code.m3ta.dev/m3tam3re/nixpkgs";
+      inputs.nixpkgs.follows = "nixpkgs";
+    };
+  };
+
+  outputs = {
+    self,
+    nixpkgs,
+    home-manager,
+    m3ta-nixpkgs,
+    ...
+  }: {
+    nixosConfigurations = {
+      myhost = nixpkgs.lib.nixosSystem {
+        system = "x86_64-linux";
+        modules = [
+          ./hardware-configuration.nix
+
+          # Import m3ta-nixpkgs modules
+          m3ta-nixpkgs.nixosModules.default
+
+          # Apply overlay
+          ({pkgs, ...}: {
+            nixpkgs.overlays = [m3ta-nixpkgs.overlays.default];
+
+            # Packages from m3ta-nixpkgs are now available
+            environment.systemPackages = with pkgs; [
+              code2prompt
+              zellij-ps
+            ];
+          })
+
+          # Home Manager integration
+          home-manager.nixosModules.home-manager
+          {
+            home-manager.useGlobalPkgs = true;
+            home-manager.useUserPackages = true;
+            home-manager.users.myusername = {
+              imports = [m3ta-nixpkgs.homeManagerModules.default];
+              home.packages = with pkgs; [
+                launch-webapp
+              ];
+            };
+          }
+        ];
+      };
+    };
+  };
+}
+```
+
+#### Option 2: Standalone Home Manager
+
+```nix
+{
+  description = "My Home Manager configuration";
+
+  inputs = {
+    nixpkgs.url = "github:NixOS/nixpkgs/nixos-unstable";
+    home-manager.url = "github:nix-community/home-manager";
+
+    m3ta-nixpkgs = {
+      url = "git+https://code.m3ta.dev/m3tam3re/nixpkgs";
+      inputs.nixpkgs.follows = "nixpkgs";
+    };
+  };
+
+  outputs = {
+    self,
+    nixpkgs,
+    home-manager,
+    m3ta-nixpkgs,
+  }: let
+    system = "x86_64-linux";
+    pkgs = import nixpkgs {
+      inherit system;
+      overlays = [m3ta-nixpkgs.overlays.default];
+    };
+  in {
+    homeConfigurations.myusername = home-manager.lib.homeManagerConfiguration {
+      inherit pkgs;
+      modules = [
+        m3ta-nixpkgs.homeManagerModules.default
+        {
+          home.username = "myusername";
+          home.homeDirectory = "/home/myusername";
+          home.packages = with pkgs; [
+            code2prompt
+            zellij-ps
+          ];
+          programs.home-manager.enable = true;
+        }
+      ];
+    };
+  };
+}
+```
+
+## Quick Usage
+
+### Using Packages Directly
+
+Without adding to your configuration:
+
+```bash
+# Build a package
+nix build git+https://code.m3ta.dev/m3tam3re/nixpkgs#code2prompt
+
+# Run a package
+nix run git+https://code.m3ta.dev/m3tam3re/nixpkgs#zellij-ps
+
+# List all available packages
+nix flake show git+https://code.m3ta.dev/m3tam3re/nixpkgs
+```
+
+### Using Packages in Configuration
+
+After applying overlay:
+
+```nix
+# System-wide (NixOS)
+environment.systemPackages = with pkgs; [
+  code2prompt
+  zellij-ps
+];
+
+# User-only (Home Manager)
+home.packages = with pkgs; [
+  launch-webapp
+];
+```
+
+### Using Modules
+
+```nix
+# Import all modules
+imports = [
+  m3ta-nixpkgs.nixosModules.default
+];
+
+# Or import specific module
+imports = [
+  m3ta-nixpkgs.nixosModules.mem0
+];
+
+# Configure module
+m3ta.mem0 = {
+  enable = true;
+  port = 8000;
+};
+```
+
+## Common Tasks
+
+### Install a Package System-Wide
+
+```nix
+# /etc/nixos/configuration.nix
+{pkgs, ...}: {
+  environment.systemPackages = with pkgs; [
+    code2prompt
+    hyprpaper-random
+  ];
+}
+
+# Apply
+sudo nixos-rebuild switch
+```
+
+### Install a Package for Your User
+
+```nix
+# home.nix
+{pkgs, ...}: {
+  home.packages = with pkgs; [
+    launch-webapp
+    zellij-ps
+  ];
+}
+
+# Apply
+home-manager switch
+```
+
+### Enable a NixOS Module
+
+```nix
+# /etc/nixos/configuration.nix
+{config, ...}: {
+  imports = [
+    m3ta-nixpkgs.nixosModules.default
+  ];
+
+  m3ta.mem0 = {
+    enable = true;
+    port = 8000;
+  };
+
+  # Apply
+  # sudo nixos-rebuild switch
+}
+```
+
+### Enable a Home Manager Module
+
+```nix
+# home.nix
+{config, ...}: {
+  imports = [
+    m3ta-nixpkgs.homeManagerModules.default
+  ];
+
+  m3ta.cli.zellij-ps = {
+    enable = true;
+  };
+
+  # Apply
+  # home-manager switch
+}
+```
+
+### Use Port Management
+
+```nix
+{config, ...}: {
+  m3ta.ports = {
+    enable = true;
+    definitions = {
+      nginx = 80;
+      grafana = 3000;
+    };
+    hostOverrides.laptop = {
+      nginx = 8080;
+    };
+    currentHost = config.networking.hostName;
+  };
+
+  services.nginx = {
+    enable = true;
+    httpConfig = ''
+      server {
+        listen ${toString (config.m3ta.ports.get "nginx")};
+        root /var/www;
+      }
+    '';
+  };
+}
+```

+# Port Management Guide
+
+Managing service ports across multiple hosts with the `m3ta.ports` module.
+
+## Overview
+
+The port management module provides a centralized way to define service ports that can have host-specific overrides. This prevents port conflicts and makes it easy to manage services across multiple machines.
+
+## Basic Usage
+
+### Enable Port Management
+
+```nix
+{config, ...}: {
+  m3ta.ports = {
+    enable = true;
+
+    # Define default ports
+    definitions = {
+      nginx = 80;
+      grafana = 3000;
+      prometheus = 9090;
+      homepage = 8080;
+    };
+
+    # Define host-specific overrides
+    hostOverrides = {
+      laptop = {
+        nginx = 8080;       # Override on laptop
+        homepage = 3001;    # Override on laptop
+      };
+      server = {
+        homepage = 3002;    # Override on server
+      };
+    };
+
+    # Set current host (determines which overrides to use)
+    currentHost = config.networking.hostName;
+  };
+}
+```
+
+### Using Ports
+
+```nix
+{config, ...}: {
+  services.nginx = {
+    enable = true;
+    httpConfig = ''
+      server {
+        listen ${toString (config.m3ta.ports.get "nginx")};
+        root /var/www;
+      }
+    '';
+  };
+
+  services.grafana = {
+    enable = true;
+    settings.server.http_port = config.m3ta.ports.get "grafana";
+  };
+}
+```
+
+## Module Options

+  prometheus = 9090;
+};
+```
+
+### `m3ta.ports.hostOverrides`
+
+Host-specific port overrides.
+
+- Type: `attrsOf (attrsOf int)`
+- Default: `{}`
+
+```nix
+hostOverrides = {
+  laptop = {
+    nginx = 8080;
+    grafana = 3001;
+  };
+  server = {
+    grafana = 3002;
+  };
+};
+```
+
+### `m3ta.ports.currentHost`
+
+Current hostname. Determines which overrides to apply.
+
+- Type: `string`
+- Example: `config.networking.hostName`
+
+```nix
+currentHost = "laptop";  # Use laptop overrides
+```
+
+### `m3ta.ports.generateEnvVars` (Home Manager only)
+
+Generate environment variables from ports.
+
+- Type: `boolean`
+- Default: `false` (Home Manager)
+- NixOS: Not available
+
+When enabled, generates environment variables like:
+- `PORT_NGINX=8080`
+- `PORT_GRAFANA=3000`
+
+## Functions
+
+### `config.m3ta.ports.get "service"`
+
+Get port for a service with host-specific override.
+
+```nix
+services.nginx = {
+  port = config.m3ta.ports.get "nginx";
+};
+```
+
+If current host is `laptop` and `hostOverrides.laptop.nginx = 8080`, returns `8080`.
+If no override, returns default `80`.
+
+### `config.m3ta.ports.getHostPorts "hostname"`
+
+Get all ports for a specific host.
+
+```nix
+# Get all ports for laptop
+laptopPorts = config.m3ta.ports.getHostPorts "laptop";
+# Returns: { nginx = 8080; grafana = 3000; ... }
+```
+
+### `config.m3ta.ports.listServices`
+
+List all defined service names.
+
+```nix
+allServices = config.m3ta.ports.listServices;
+# Returns: ["nginx" "grafana" "prometheus" "homepage"]
+```
+
+## Examples
+
+### NixOS Configuration
+
+```nix
+{config, ...}: {
+  # Define ports
+  m3ta.ports = {
+    enable = true;
+    definitions = {
+      nginx = 80;
+      grafana = 3000;
+      prometheus = 9090;
+      loki = 3100;
+      promtail = 9080;
+    };
+    hostOverrides.laptop = {
+      nginx = 8080;
+      grafana = 3001;
+    };
+    currentHost = config.networking.hostName;
+  };
+
+  # Use ports
+  services.nginx = {
+    enable = true;
+    httpConfig = ''
+      server {
+        listen ${toString (config.m3ta.ports.get "nginx")};
+        root /var/www;
+      }
+    '';
+  };
+
+  services.grafana = {
+    enable = true;
+    settings.server.http_port = config.m3ta.ports.get "grafana";
+  };
+
+  services.prometheus = {
+    enable = true;
+    port = config.m3ta.ports.get "prometheus";
+  };
+
+  services.loki = {
+    enable = true;
+    configuration.http_listen_port = config.m3ta.ports.get "loki";
+  };
+}
+```
+
+### Home Manager Configuration
+
+```nix
+{config, ...}: {
+  # Define ports
+  m3ta.ports = {
+    enable = true;
+    definitions = {
+      dev-server = 3000;
+      nextjs = 3001;
+      vite = 5173;
+    };
+    hostOverrides.desktop = {
+      vite = 5174;
+    };
+    currentHost = "desktop";
+    generateEnvVars = true;  # Generate env vars
+  };
+
+  # Ports are now available as env vars
+  # PORT_DEV_SERVER=3000
+  # PORT_NEXTJS=3001
+  # PORT_VITE=5174
+
+  home.sessionVariables = {
+    DEV_PORT = toString (config.m3ta.ports.get "dev-server");
+  };
+}
+```
+
+### With Custom Modules
+
+Using ports with custom modules (e.g., `m3ta.mem0`):
+
+```nix
+{config, ...}: {
+  # Define ports
+  m3ta.ports = {
+    enable = true;
+    definitions = {
+      mem0 = 8000;
+      qdrant = 6333;
+    };
+    hostOverrides.laptop = {
+      mem0 = 8080;
+    };
+    currentHost = config.networking.hostName;
+  };
+
+  # Use with mem0 module
+  m3ta.mem0 = {
+    enable = true;
+    port = config.m3ta.ports.get "mem0";  # 8000 or 8080 on laptop
+  };
+
+  # Use with qdrant service
+  services.qdrant = {
+    enable = true;
+    port = config.m3ta.ports.get "qdrant";
+  };
+}
+```
+
+### Port File Generation
+
+Generate a JSON file with all ports:
+
+```nix
+{config, pkgs, ...}: {
+  m3ta.ports = {
+    enable = true;
+    definitions = {
+      service1 = 80;
+      service2 = 443;
+    };
+    currentHost = config.networking.hostName;
+  };
+
+  # Generate port file
+  environment.etc."m3ta/ports.json".text = builtins.toJSON (
+    config.m3ta.ports.getHostPorts config.networking.hostName
+  );
+}
+```
+
+## Advanced Usage
+
+### Conditional Configuration
+
+```nix
+{config, ...}: {
+  services.nginx = {
+    enable = true;
+
+    # Only open firewall if binding to non-localhost
+    httpConfig = let
+      port = config.m3ta.ports.get "nginx";
+    in ''
+      server {
+        listen ${toString port};
+      }
+    '';
+  };
+
+  networking.firewall.allowedTCPPorts =
+    if config.m3ta.ports.get "nginx" == 80
+    then [80]
+    else [];
+}
+```
+
+### Port Ranges
+
+```nix
+definitions = {
+  service-start = 8000;
+  service-end = 8999;
+};
+
+# Use in config
+services.my-app = {
+  portRange = [
+    config.m3ta.ports.get "service-start"
+    config.m3ta.ports.get "service-end"
+  ];
+};
+```
+
+### Dynamic Port Allocation
+
+```nix
+{config, ...}: {
+  m3ta.ports = {
+    enable = true;
+    definitions = {
+      # Reserve port ranges
+      app-range-start = 9000;
+      app-range-end = 9999;
+    };
+    currentHost = config.networking.hostName;
+  };
+
+  # Calculate next available port
+  services.my-app = {
+    port = config.m3ta.ports.get "app-range-start" + 0;
+  };
+
+  services.my-other-app = {
+    port = config.m3ta.ports.get "app-range-start" + 1;
+  };
+}
+```
+
+## Best Practices
+
+### Use Descriptive Service Names
+
+```nix
+# Good
+definitions = {
+  nginx = 80;
+  grafana = 3000;
+  prometheus-ui = 9090;
+  prometheus-push = 9091;
+};
+
+# Avoid
+definitions = {
+  p1 = 80;
+  p2 = 3000;
+  p3 = 9090;
+};
+```
+
+### Group Related Services
+
+```nix
+definitions = {
+  # Monitoring stack
+  grafana = 3000;
+  prometheus = 9090;
+  loki = 3100;
+  promtail = 9080;
+
+  # Web services
+  nginx = 80;
+  homepage = 8080;
+
+  # Databases
+  postgres = 5432;
+  redis = 6379;
+  qdrant = 6333;
+};
+```
+
+### Document Overrides
+
+```nix
+hostOverrides = {
+  # Laptop: Running multiple dev servers, use higher ports
+  laptop = {
+    nginx = 8080;
+    dev-server = 3000;
+  };
+
+  # Server: Production, use standard ports
+  server = {
+    nginx = 80;
+    dev-server = null;  # Disable on server
+  };
+};
+```
+
+### Handle Missing Ports
+
+```nix
+services.some-service = {
+  enable = true;
+  port = config.m3ta.ports.get "some-service" or 8080;
+};
+```
+
+## Troubleshooting
+
+### Service Not Found
+
+Error: `Service "foo" not defined`
+
+Solution: Add service to `definitions`:
+
+```nix
+definitions = {
+  foo = 8080;
+};
+```
+
+### Current Host Not Set
+
+Error: `currentHost not set`
+
+Solution: Set `currentHost`:
+
+```nix
+currentHost = config.networking.hostName;
+```
+
+### Port Conflict
+
+Issue: Two services trying to use same port.
+
+Solution: Define both in port management:
+
+```nix
+definitions = {
+  service1 = 8080;
+  service2 = 8081;  # Different port
+};
+```
+
+## Migration from Hardcoded Ports
+
+### Before
+
+```nix
+services.nginx = {
+  enable = true;
+  httpConfig = ''
+    server {
+      listen 80;
+    }
+  '';
+};
+
+services.grafana = {
+  enable = true;
+  settings.server.http_port = 3000;
+};
+```
+
+### After
+
+```nix
+m3ta.ports = {
+  enable = true;
+  definitions = {
+    nginx = 80;
+    grafana = 3000;
+  };
+  currentHost = config.networking.hostName;
+};
+
+services.nginx = {
+  enable = true;
+  httpConfig = ''
+    server {
+      listen ${toString (config.m3ta.ports.get "nginx")};
+    }
+  '';
+};
+
+services.grafana = {
+  enable = true;
+  settings.server.http_port = config.m3ta.ports.get "grafana";
+};
+```

+
+How to use NixOS and Home Manager modules from m3ta-nixpkgs.
+
+## Overview
+
+Modules in m3ta-nixpkgs provide reusable configuration for NixOS (system-level) and Home Manager (user-level) settings. All modules use the `m3ta.*` namespace.

+
+## Common Patterns
+
+### Module Configuration
+
+All modules follow this pattern:
+
+```nix
+{ config, lib, pkgs, ... }:
+with lib; let
+  cfg = config.m3ta.myModule;
+in {
+  options.m3ta.myModule = {
+    enable = mkEnableOption "description";
+    # ... other options
+  };
+
+  config = mkIf cfg.enable {
+    # ... configuration
+  };
+}
+```
+
+### Conditional Configuration
+
+Use `mkIf` to conditionally apply config:
+
+```nix
+config = mkIf cfg.enable {
+  # Only applied when cfg.enable = true
+  services.my-service = {
+    enable = true;
+  };
+}
+```
+
+### Multiple Conditions
+
+Use `mkMerge` for multiple conditions:
+
+```nix
+config = mkMerge [
+  (mkIf cfg.feature1.enable {
+    # Applied when feature1 is enabled
+  })
+  (mkIf cfg.feature2.enable {
+    # Applied when feature2 is enabled
+  })
+];
+```
+
+### Optional Dependencies
+
+```nix
+options.m3ta.myModule = {
+  enable = mkEnableOption "my module";
+  package = mkOption {
+    type = types.package;
+    default = pkgs.defaultPackage;
+  };
+};
+
+config = mkIf cfg.enable {
+  services.my-service = {
+    package = cfg.package;
+  };
+};
+```
+
+## Configuration Examples
+
+### Minimal NixOS Configuration
+
+```nix
+{pkgs, ...}: {
+  imports = [
+    m3ta-nixpkgs.nixosModules.default
+  ];
+
+  m3ta.ports = {
+    enable = true;
+    definitions = {
+      my-service = 8080;
+    };
+    currentHost = "laptop";
+  };
+
+  services.my-custom-service = {
+    enable = true;
+    port = config.m3ta.ports.get "my-service";
+  };
+}
+```

+
+## Combining with Other Flakes
+
+### Using Multiple Module Sources
+
+```nix
+{config, ...}: {
+  imports = [
+    # m3ta-nixpkgs modules
+    m3ta-nixpkgs.nixosModules.default
+
+    # Other flake modules
+    inputs.impermanence.nixosModules.impermanence
+    inputs.sops-nix.nixosModules.sops
+  ];
+
+  # Configure all modules
+  m3ta.ports = {
+    enable = true;
+    definitions = {nginx = 80;};
+    currentHost = config.networking.hostName;
+  };
+
+  environment.persistence = {
+    "/persist" = {
+      directories = ["/var/lib/mem0"];
+    };
+  };
+}
+```
+
+### Using with Secrets
+
+```nix
+{config, ...}: {
+  imports = [
+    m3ta-nixpkgs.nixosModules.default
+    inputs.sops-nix.nixosModules.sops
+  ];
+
+  sops.secrets = {
+    openai-api-key = {};
+  };
+
+  m3ta.mem0 = {
+    enable = true;
+    llm = {
+      apiKeyFile = config.sops.secrets.openai-api-key.path;
+    };
+  };
+}
+```
+
+## Troubleshooting
+
+### Module Not Found
+
+Error: `error: The option 'm3ta.mymodule' does not exist`
+
+**Solutions**:
+1. Make sure you imported the module:
+
+```nix
+imports = [
+  m3ta-nixpkgs.nixosModules.default
+];
+```
+
+2. Check module name is correct
+
+```nix
+# Correct
+m3ta.mem0.enable = true;
+
+# Wrong
+m3ta.mymodule.enable = true;  # Doesn't exist
+```
+
+### Option Type Mismatch
+
+Error: `type mismatch at 'm3ta.mymodule.enable', expected a boolean but got a list`
+
+**Solution**: Check option types in documentation
+
+```nix
+# Correct
+m3ta.mymodule.enable = true;
+
+# Wrong
+m3ta.mymodule.enable = [true];  # Should be boolean
+```
+
+### Port Not Defined
+
+Error: `Service "foo" not defined`
+
+**Solution**: Add to port definitions
+
+```nix
+m3ta.ports = {
+  definitions = {
+    foo = 8080;  # Add this
+  };
+};
+```
+
+## Best Practices
+
+### Use Namespaces
+
+Always use the `m3ta.*` namespace:
+
+```nix
+# Good
+m3ta.mem0.enable = true;
+
+# Bad (potential conflicts)
+mem0.enable = true;
+```
+
+### Document Your Configuration
+
+Add comments explaining module usage:
+
+```nix
+# Port management for multi-host setup
+m3ta.ports = {
+  enable = true;
+  definitions = {
+    nginx = 80;
+    grafana = 3000;
+  };
+  hostOverrides.laptop = {
+    nginx = 8080;  # Use different port on laptop
+  };
+  currentHost = config.networking.hostName;
+};
+
+# Mem0 AI memory service
+m3ta.mem0 = {
+  enable = true;
+  port = config.m3ta.ports.get "mem0";
+};
+```
+
+### Test Configuration
+
+```bash
+# Test NixOS configuration without applying
+sudo nixos-rebuild test --flake .#hostname
+
+# Check configuration
+nix flake check
+
+# Show all options
+nix eval .#nixosConfigurations.hostname.config.m3ta --apply builtins.attrNames
+```

+# zellij-ps Home Manager Module
+
+Zellij project switcher for Home Manager.
+
+## Overview
+
+This module configures the zellij-ps tool, a Fish script that provides a fast, interactive way to switch between project folders in Zellij terminal multiplexer sessions.
+
+## Quick Start
+
+```nix
+{config, ...}: {
+  imports = [m3ta-nixpkgs.homeManagerModules.default];
+
+  m3ta.cli.zellij-ps = {
+    enable = true;
+  };
+}
+```
+
+## Module Options
+
+### `m3ta.cli.zellij-ps.enable`
+
+Enable zellij-ps module.
+
+- Type: `boolean`
+- Default: `false`
+
+### `m3ta.cli.zellij-ps.package`
+
+Custom package to use.
+
+- Type: `package`
+- Default: `pkgs.zellij-ps`
+
+## Usage
+
+After enabling, zellij-ps will be available in your path:
+
+```bash
+# Run from outside Zellij to start a project session
+zellij-ps
+
+# Or pass a project path directly
+zellij-ps ~/projects/my-project
+```
+
+### Basic Usage
+
+1. Set `$PROJECT_FOLDERS` in your shell config (e.g., `~/projects:~/code`)
+2. Run `zellij-ps` from outside a Zellij session
+3. Use fzf to select a project from your configured folders
+4. Zellij will create or attach to a session for that project
+
+## Configuration
+
+### Custom Package
+
+Use a custom or modified package:
+
+```nix
+m3ta.cli.zellij-ps = {
+  enable = true;
+  package = pkgs.callPackage ./my-zellij-ps {};
+};
+```
+
+## Dependencies
+
+The module ensures these are installed:
+
+- `fish` - Shell for script execution
+- `fd` - Fast file search
+- `fzf` - Fuzzy finder
+- `zellij` - Terminal multiplexer

+# ports Home Manager Module
+
+Port management module for Home Manager.
+
+## Overview
+
+This module provides centralized port management for user-level services, similar to the NixOS version but with additional support for generating environment variables.
+
+See [Port Management Guide](../../guides/port-management.md) for detailed usage.
+
+## Quick Start
+
+```nix
+{config, ...}: {
+  m3ta.ports = {
+    enable = true;
+
+    # Define default ports
+    definitions = {
+      dev-server = 3000;
+      nextjs = 3001;
+      vite = 5173;
+    };
+
+    # Host-specific overrides
+    hostOverrides = {
+      laptop = {
+        vite = 5174;
+      };
+    };
+
+    # Current host
+    currentHost = "desktop";
+
+    # Generate environment variables (Home Manager only)
+    generateEnvVars = true;
+  };
+}
+```
+
+## Module Options
+
+### `m3ta.ports.enable`
+
+Enable port management.
+
+- Type: `boolean`
+- Default: `false`
+
+### `m3ta.ports.definitions`
+
+Default port definitions.
+
+- Type: `attrsOf int`
+- Default: `{}`
+
+Example:
+
+```nix
+definitions = {
+  dev-server = 3000;
+  nextjs = 3001;
+  vite = 5173;
+};
+```
+
+### `m3ta.ports.hostOverrides`
+
+Host-specific port overrides.
+
+- Type: `attrsOf (attrsOf int)`
+- Default: `{}`
+
+Example:
+
+```nix
+hostOverrides = {
+  laptop = {
+    vite = 5174;
+  };
+  desktop = {
+    vite = 5173;
+  };
+};
+```
+
+### `m3ta.ports.currentHost`
+
+Current hostname.
+
+- Type: `string`
+- Example: `"desktop"`
+
+### `m3ta.ports.generateEnvVars`
+
+Generate environment variables from ports.
+
+- Type: `boolean`
+- Default: `false`
+- Home Manager only
+
+When enabled, generates environment variables like:
+
+```bash
+PORT_DEV_SERVER=3000
+PORT_NEXTJS=3001
+PORT_VITE=5173
+```
+
+## Functions
+
+### `config.m3ta.ports.get "service"`
+
+Get port for a service with host-specific override.
+
+```nix
+home.sessionVariables = {
+  DEV_PORT = toString (config.m3ta.ports.get "dev-server");
+};
+```
+
+### `config.m3ta.ports.getHostPorts "hostname"`
+
+Get all ports for a specific host.
+
+```nix
+laptopPorts = config.m3ta.ports.getHostPorts "laptop";
+# Returns: { dev-server = 3000; vite = 5174; ... }
+```
+
+### `config.m3ta.ports.listServices`
+
+List all defined service names.
+
+```nix
+allServices = config.m3ta.ports.listServices;
+# Returns: ["dev-server" "nextjs" "vite"]
+```
+
+## Environment Variables
+
+When `generateEnvVars = true`, the following environment variables are generated:
+
+```
+PORT_<SERVICE_UPPERCASE>=<port_number>
+```
+
+Example:
+
+```nix
+m3ta.ports = {
+  enable = true;
+  definitions = {
+    dev-server = 3000;
+    nextjs = 3001;
+  };
+  generateEnvVars = true;
+};
+```
+
+Generates:
+
+```bash
+PORT_DEV_SERVER=3000
+PORT_NEXTJS=3001
+```
+
+You can then use these in scripts:
+
+```bash
+#!/usr/bin/env bash
+# Use environment variable directly
+npm start --port=$PORT_DEV_SERVER
+```
+
+## Usage Examples
+
+### Basic Usage
+
+```nix
+{config, ...}: {
+  m3ta.ports = {
+    enable = true;
+    definitions = {
+      dev-server = 3000;
+    };
+    currentHost = "desktop";
+  };
+
+  home.sessionVariables = {
+    DEV_PORT = toString (config.m3ta.ports.get "dev-server");
+  };
+}
+```
+
+### With Environment Variables
+
+```nix
+{config, ...}: {
+  m3ta.ports = {
+    enable = true;
+    definitions = {
+      dev-server = 3000;
+      nextjs = 3001;
+      vite = 5173;
+    };
+    currentHost = "desktop";
+    generateEnvVars = true;
+  };
+
+  # Now available as environment variables
+  # PORT_DEV_SERVER=3000
+  # PORT_NEXTJS=3001
+  # PORT_VITE=5173
+}
+```
+
+### With Multi-Host Setup
+
+```nix
+{config, ...}: {
+  m3ta.ports = {
+    enable = true;
+    definitions = {
+      dev-server = 3000;
+      vite = 5173;
+    };
+    hostOverrides = {
+      laptop = {
+        vite = 5174;
+      };
+      desktop = {
+        vite = 5173;
+      };
+    };
+    currentHost = config.networking.hostName;
+    generateEnvVars = true;
+  };
+}
+```
+
+### With Shell Scripts
+
+Create `~/.config/zellij/scripts/dev.ksh`:
+
+```ksh
+#!/usr/bin/env ksh
+# Start dev server using environment variable
+cd ~/projects/my-app
+npm start --port=$PORT_DEV_SERVER
+```
+
+## Difference from NixOS Module
+
+The Home Manager version has one additional feature:
+
+### `generateEnvVars`
+
+Not available in NixOS module. Generates environment variables for all defined ports:
+
+```nix
+# Home Manager
+m3ta.ports.generateEnvVars = true;  # Available
+
+# NixOS
+# Not available
+```

+## Service Management
+
+### Start/Stop/Restart
+
+```bash
+# Start service
+sudo systemctl start mem0
+
+# Stop service
+sudo systemctl stop mem0
+
+# Restart service
+sudo systemctl restart mem0
+
+# Check status
+sudo systemctl status mem0
+```
+
+### View Logs
+
+```bash
+# View logs
+sudo journalctl -u mem0 -f
+
+# View last 100 lines
+sudo journalctl -u mem0 -n 100
+```
+
+### Service File
+
+The module creates a systemd service at `/etc/systemd/system/mem0.service` with:
+
+- Security hardening enabled
+- Automatic restart on failure
+- Proper user/group setup
+
+## API Usage
+
+### Add Memory
+
+```bash
+curl -X POST http://localhost:8000/v1/memories \
+  -H "Content-Type: application/json" \
+  -d '{
+    "content": "User prefers coffee over tea",
+    "metadata": {"user_id": "123"}
+  }'
+```
+
+### Search Memories
+
+```bash
+curl http://localhost:8000/v1/memories/search?q=coffee
+```
+
+### Update Memory
+
+```bash
+curl -X PATCH http://localhost:8000/v1/memories/memory_id \
+  -H "Content-Type: application/json" \
+  -d '{
+    "content": "User prefers coffee over tea, but also likes chai"
+  }'
+```
+
+### Delete Memory
+
+```bash
+curl -X DELETE http://localhost:8000/v1/memories/memory_id
+```
+
+## Dependencies
+
+### Required Services
+
+Depending on your configuration, you may need:
+
+- **qdrant** service (if using qdrant vector store)
+- **postgresql** with pgvector (if using pgvector)
+- **chroma** service (if using chroma)
+- **ollama** (if using local LLMs)
+
+### Example: Qdrant
+
+```nix
+services.qdrant = {
+  enable = true;
+  port = 6333;
+};
+```
+
+### Example: PostgreSQL
+
+```nix
+services.postgresql = {
+  enable = true;
+  enableTCPIP = true;
+  package = pkgs.postgresql_15;
+
+  extensions = ["pgvector"];
+
+  settings = {
+    port = 5432;
+  };
+};
+```
+
+## Firewall
+
+The module automatically opens the firewall port if binding to non-localhost addresses:
+
+```nix
+# Opens port if host is not "127.0.0.1" or "localhost"
+m3ta.mem0 = {
+  enable = true;
+  host = "0.0.0.0";  # Binds to all interfaces
+  port = 8000;
+};
+# Firewall automatically opens port 8000
+```
+
+## Security
+
+### User/Group
+
+Creates dedicated user and group:
+
+- User: `mem0`
+- Group: `mem0`
+- Home: `/var/lib/mem0`
+
+### Hardening
+
+Systemd service includes security hardening:
+
+- `NoNewPrivileges`
+- `PrivateTmp`
+- `ProtectSystem=strict`
+- `ProtectHome=true`
+- `RestrictRealtime=true`
+- `RestrictNamespaces=true`
+- `LockPersonality=true`
+
+### Secrets
+
+Use `apiKeyFile` for API keys instead of plain text:
+
+```nix
+# Good
+llm.apiKeyFile = "/run/secrets/openai-api-key";
+
+# Bad (insecure)
+llm.apiKey = "sk-xxx";
+```
+
+## Troubleshooting
+
+### Service Won't Start
+
+Check logs:
+
+```bash
+sudo journalctl -u mem0 -n 50
+```
+
+Common issues:
+
+1. **API key missing**: Ensure `apiKeyFile` exists and is readable
+2. **Vector store unavailable**: Ensure qdrant/other store is running
+3. **Port in use**: Check if port is available
+
+### API Not Responding
+
+Check service status:
+
+```bash
+sudo systemctl status mem0
+
+# Check if port is open
+ss -tuln | grep 8000
+```
+
+### Memory Issues
+
+Increase memory limit in systemd override:
+
+```bash
+sudo systemctl edit mem0
+
+[Service]
+MemoryMax=2G
+```

+
+See [Port Management Guide](../../guides/port-management.md) for detailed usage.
+
+## Quick Start
+
+```nix
+{config, ...}: {
+  m3ta.ports = {
+    enable = true;
+
+    # Define default ports
+    definitions = {
+      nginx = 80;
+      grafana = 3000;
+      prometheus = 9090;
+    };
+
+    # Host-specific overrides
+    hostOverrides = {
+      laptop = {
+        nginx = 8080;
+        grafana = 3001;
+      };
+    };
+
+    # Current host

+# zellij-ps
+
+A Zellij project switcher for quickly navigating and opening project workspaces.
+
+## Description
+
+zellij-ps is a Fish script inspired by ThePrimeagen's tmux-sessionizer. It provides a fast, interactive way to switch between project folders in Zellij. Using `fd` for fast directory discovery and `fzf` for fuzzy selection, it helps you quickly jump into your work.
+
+The script searches through your configured project folders (`$PROJECT_FOLDERS`) and either creates a new Zellij session for the selected project or attaches to an existing one.
+
+## Installation
+
+### Via Overlay
+
+```nix
+{pkgs, ...}: {
+  environment.systemPackages = with pkgs; [
+    zellij-ps
+  ];
+}
+```
+
+### Direct Reference
+
+```nix
+{pkgs, ...}: {
+  environment.systemPackages = with pkgs; [
+    inputs.m3ta-nixpkgs.packages.${pkgs.system}.zellij-ps
+  ];
+}
+```
+
+### Run Directly
+
+```bash
+nix run git+https://code.m3ta.dev/m3tam3re/nixpkgs#zellij-ps
+```
+
+## Usage
+
+### Basic Usage
+
+```bash
+# Run from outside Zellij to start a project session
+zellij-ps
+
+# Or pass a project path directly
+zellij-ps ~/projects/my-project
+```
+
+This will:
+
+1. Search through your `$PROJECT_FOLDERS` for directories
+2. Open fzf for fuzzy project selection (if no argument provided)
+3. Create a new Zellij session or attach to existing one for the selected project
+
+### Configuration
+
+Set your project folders in your shell configuration:
+
+**Fish example:**
+```fish
+set -x PROJECT_FOLDERS ~/projects:~/code:~/work
+```
+
+**Bash/Zsh example:**
+```bash
+export PROJECT_FOLDERS="$HOME/projects:$HOME/code:$HOME/work"
+```
+
+Folders should be delimited by `:` and can include `~` for home directory.
+
+## Home Manager Module
+
+### Enable Module
+
+```nix
+{config, ...}: {
+  imports = [m3ta-nixpkgs.homeManagerModules.default];
+
+  m3ta.cli.zellij-ps = {
+    enable = true;
+  };
+}
+```
+
+### Module Options
+
+#### `m3ta.cli.zellij-ps.enable`
+
+Enable the zellij-ps module.
+
+- Type: `boolean`
+- Default: `false`
+
+#### `m3ta.cli.zellij-ps.package`
+
+Custom package to use.
+
+- Type: `package`
+- Default: `pkgs.zellij-ps`
+
+## Requirements
+
+### System Requirements
+
+- Linux or Unix-like system
+- Configured `$PROJECT_FOLDERS` environment variable
+
+## Platform Support
+
+- Linux (primary)
+- macOS (may work)
+- Windows (not supported)
+
+## Build Information
+
+- **Version**: 0.1.0
+- **Type**: Fish script
+- **License**: MIT
+- **Inspired by**: [ThePrimeagen's tmux-sessionizer](https://github.com/ThePrimeagen/.dotfiles/blob/master/bin/.local/scripts/tmux-sessionizer)
+- **Source**: [Gitea](https://code.m3ta.dev/m3tam3re/helper-scripts)
+
+## Source Code
+
+The script is available at:
+
+```
+https://code.m3ta.dev/m3tam3re/helper-scripts/src/branch/main/zellij-ps.fish
+```
+
+## Troubleshooting
+
+### No Projects Found
+
+If fzf shows no results, check your `$PROJECT_FOLDERS` variable:
+
+```bash
+# In fish
+echo $PROJECT_FOLDERS
+
+# In bash/zsh
+echo $PROJECT_FOLDERS
+```
+
+Ensure the folders exist and contain subdirectories.
+
+### Already in Zellij Session
+
+If you're already inside a Zellij session, you'll see:
+
+```
+You are in a Zellij Session!
+Please use the session manager to switch sessions.
+```
+
+Use Zellij's built-in session manager (`Ctrl+p` → `s`) to switch sessions instead.
+
+### fd Not Found
+
+Error: `fd: command not found`
+
+**Solution**: Ensure fd is installed:
+
+```nix
+{pkgs, ...}: {
+  environment.systemPackages = with pkgs; [
+    fd
+  ];
+}
+```
+
+### Fish Not Found
+
+Error: `fish: command not found`
+
+**Solution**: Ensure Fish is installed:
+
+```nix
+{pkgs, ...}: {
+  programs.fish = {
+    enable = true;
+  };
+}
+```
+
+### fzf Not Working
+
+Ensure fzf is installed and configured:
+
+```bash
+# Check fzf
+which fzf
+
+# Test fzf
+echo -e "item1\nitem2\nitem3" | fzf
+```

+# Code Patterns and Anti-Patterns
+
+Common code patterns and anti-patterns used in m3ta-nixpkgs.
+
+## Overview
+
+This document outlines recommended patterns and common pitfalls when working with m3ta-nixpkgs.
+
+## Code Patterns
+
+### Package Pattern
+
+#### CallPackage Registry
+
+Use `callPackage` for lazy evaluation:
+
+```nix
+# Good - pkgs/default.nix
+{
+  inherit (pkgs) callPackage;
+} rec {
+  code2prompt = callPackage ./code2prompt {};
+  mem0 = callPackage ./mem0 {};
+}
+```
+
+#### Meta Fields
+
+Always include complete `meta` information:
+
+```nix
+# Good
+meta = with lib; {
+  description = "My awesome package";
+  homepage = "https://github.com/author/package";
+  changelog = "https://github.com/author/package/releases/tag/v${version}";
+  license = licenses.mit;
+  platforms = platforms.linux;
+  mainProgram = "program-name";
+};
+```
+
+### Module Pattern
+
+#### Standard Module Structure
+
+```nix
+# Good
+{ config, lib, pkgs, ... }:
+with lib; let
+  cfg = config.m3ta.myModule;
+in {
+  options.m3ta.myModule = {
+    enable = mkEnableOption "my module";
+    # ... options
+  };
+
+  config = mkIf cfg.enable {
+    # ... configuration
+  };
+}
+```
+
+#### mkEnableOption
+
+Always use `mkEnableOption` for enable flags:
+
+```nix
+# Good
+options.m3ta.myModule = {
+  enable = mkEnableOption "my module";
+};
+
+# Bad
+options.m3ta.myModule.enable = mkOption {
+  type = types.bool;
+  default = false;
+};
+```
+
+#### Conditional Configuration
+
+Use `mkIf` for conditional config:
+
+```nix
+# Good
+config = mkIf cfg.enable {
+  services.my-service.enable = true;
+};
+```
+
+#### Multiple Conditions
+
+Use `mkMerge` for multiple conditions:
+
+```nix
+# Good
+config = mkMerge [
+  (mkIf cfg.feature1.enable {
+    # config for feature1
+  })
+  (mkIf cfg.feature2.enable {
+    # config for feature2
+  })
+];
+```
+
+### Import Pattern
+
+#### Multi-line Imports
+
+Multi-line, trailing commas:
+
+```nix
+# Good
+{
+  lib,
+  stdenv,
+  fetchFromGitHub,
+}:
+```
+
+#### Explicit Dependencies
+
+```nix
+# Good
+{
+  lib,
+  stdenv,
+  openssl,
+  pkg-config,
+}:
+stdenv.mkDerivation {
+  buildInputs = [openssl pkg-config];
+}
+```
+
+## Anti-Patterns
+
+### lib.fakeHash in Commits
+
+**Bad**: Committing `lib.fakeHash`
+
+```nix
+# Bad - Never commit this!
+src = fetchFromGitHub {
+  hash = lib.fakeHash;
+};
+```
+
+**Solution**: Build to get real hash:
+
+```bash
+nix build .#your-package
+# Copy actual hash from error message
+```
+
+### Flat Module Files
+
+**Bad**: All modules in one file
+
+```nix
+# Bad - Hard to maintain
+{config, lib, pkgs, ...}: {
+  options.m3ta.cli = {
+    tool1 = mkEnableOption "tool1";
+    tool2 = mkEnableOption "tool2";
+    # ... many more
+  };
+
+  config = mkMerge [
+    (mkIf config.m3ta.cli.tool1.enable {...})
+    (mkIf config.m3ta.cli.tool2.enable {...})
+    # ... many more
+  ];
+}
+```
+
+**Solution**: Organize by category
+
+```nix
+# Good - modules/home-manager/cli/
+# modules/home-manager/cli/default.nix
+{
+  imports = [
+    ./tool1.nix
+    ./tool2.nix
+  ];
+}
+```
+
+### Hardcoded Ports
+
+**Bad**: Hardcoding ports in services
+
+```nix
+# Bad
+services.nginx = {
+  enable = true;
+  httpConfig = ''
+    server {
+      listen 80;
+    }
+  '';
+};
+```
+
+**Solution**: Use port management
+
+```nix
+# Good
+m3ta.ports = {
+  enable = true;
+  definitions = {nginx = 80;};
+};
+
+services.nginx = {
+  enable = true;
+  httpConfig = ''
+    server {
+      listen ${toString (config.m3ta.ports.get "nginx")};
+    }
+  '';
+};
+```
+
+### Skipping Meta Fields
+
+**Bad**: Incomplete meta information
+
+```nix
+# Bad
+meta = {
+  description = "My package";
+};
+```
+
+**Solution**: Include all fields
+
+```nix
+# Good
+meta = with lib; {
+  description = "My awesome package";
+  homepage = "https://github.com/author/package";
+  license = licenses.mit;
+  platforms = platforms.linux;
+  mainProgram = "program-name";
+};
+```
+
+### with pkgs; in Modules
+
+**Bad**: Using `with pkgs;` at module level
+
+```nix
+# Bad
+{config, lib, pkgs, ...}: with pkgs; {
+  config.environment.systemPackages = [
+    vim
+    git
+  ];
+}
+```
+
+**Solution**: Explicit package references or limited with
+
+```nix
+# Good - Explicit references
+{config, lib, pkgs, ...}: {
+  config.environment.systemPackages = with pkgs; [
+    vim
+    git
+  ];
+}
+
+# Or - Full references
+{config, lib, pkgs, ...}: {
+  config.environment.systemPackages = [
+    pkgs.vim
+    pkgs.git
+  ];
+}
+```
+
+### Orphaned Package Directories
+
+**Bad**: Creating directory without registering
+
+```nix
+# Bad - Package not visible
+# pkgs/my-package/default.nix exists
+# But pkgs/default.nix doesn't reference it
+```
+
+**Solution**: Register in `pkgs/default.nix`
+
+```nix
+# Good
+{
+  inherit (pkgs) callPackage;
+} rec {
+  my-package = callPackage ./my-package {};
+}
+```
+
+## Type Safety
+
+### No Type Suppression
+
+**Bad**: Using `as any`
+
+```nix
+# Bad
+let
+  value = someFunction config as any;
+in
+  # ...
+```
+
+**Solution**: Fix underlying type issues
+
+```nix
+# Good
+let
+  value = someFunction config;
+in
+  # Ensure value has correct type
+```
+
+### Proper Type Definitions
+
+```nix
+# Good
+options.m3ta.myModule = {
+  enable = mkEnableOption "my module";
+
+  port = mkOption {
+    type = types.port;
+    default = 8080;
+    description = "Port to run on";
+  };
+};
+```
+
+## Naming Conventions
+
+### Package Names
+
+**Good**: `lowercase-hyphen`
+
+```nix
+code2prompt
+hyprpaper-random
+launch-webapp
+```
+
+**Bad**: CamelCase or underscores
+
+```nix
+code2Prompt      # Bad
+hyprpaper_random # Bad
+```
+
+### Variables
+
+**Good**: `camelCase`
+
+```nix
+portHelpers
+configFile
+serviceName
+```
+
+**Bad**: Snake_case or kebab-case
+
+```nix
+port_helpers    # Bad
+port-helpers   # Bad
+```
+
+### Module Options
+
+**Good**: `m3ta.*` namespace
+
+```nix
+m3ta.ports.enable = true;
+m3ta.cli.zellij-ps.enable = true;
+```
+
+**Bad**: Flat namespace
+
+```nix
+ports.enable = true;  # Potential conflict
+cli.zellij-ps.enable = true;  # Hard to find
+```
+
+## Performance
+
+### Lazy Evaluation
+
+**Good**: Use `callPackage`
+
+```nix
+# Good - Only builds requested package
+code2prompt = callPackage ./code2prompt {};
+```
+
+**Bad**: Building all packages
+
+```nix
+# Bad - Builds everything even if not used
+code2prompt = import ./code2prompt {};
+```
+
+### Selective Imports
+
+**Good**: Import only needed modules
+
+```nix
+# Good
+imports = [
+  m3ta-nixpkgs.nixosModules.mem0
+];
+```
+
+**Bad**: Importing all modules
+
+```nix
+# Bad - Imports and evaluates all modules
+imports = [
+  m3ta-nixpkgs.nixosModules.default
+];
+```
+
+## Security
+
+### No Secrets in Store
+
+**Bad**: Putting secrets in configuration
+
+```nix
+# Bad - Secret in Nix store
+m3ta.mem0.llm.apiKey = "sk-xxx";
+```
+
+**Solution**: Use secret files
+
+```nix
+# Good - Secret from file
+m3ta.mem0.llm.apiKeyFile = "/run/secrets/openai-api-key";
+```
+
+### Proper User/Group
+
+**Good**: Dedicated users for services
+
+```nix
+# Good
+users.users.mem0 = {
+  isSystemUser = true;
+  group = "mem0";
+};
+```
+
+### Service Hardening
+
+**Good**: Enable systemd hardening
+
+```nix
+# Good
+systemd.services.mem0.serviceConfig = {
+  NoNewPrivileges = true;
+  PrivateTmp = true;
+  ProtectSystem = "strict";
+  ProtectHome = true;
+};
+```
+
+## Best Practices Summary
+
+| Practice | Do | Don't |
+|----------|-----|--------|
+| Hash fetching | Get real hash from build error | Commit `lib.fakeHash` |
+| Module organization | Categorize by function | Put all in one file |
+| Port management | Use `m3ta.ports` module | Hardcode ports |
+| Meta fields | Include all fields | Skip fields |
+| Type safety | Fix type errors | Use `as any` |
+| Dependencies | Explicit declarations | Implicit deps |
+| Imports | Multi-line, trailing comma | Single-line, no comma |
+| Naming | Follow conventions | Mix styles |
+| Secrets | Use file-based | Put in config |
+| Evaluation | Lazy (`callPackage`) | Import everything |
