+# Adding Modules Guide
+
+How to add new NixOS and Home Manager modules to m3ta-nixpkgs.
+
+## Overview
+
+Modules extend your system or user configuration with reusable, declarative options. m3ta-nixpkgs uses the standard NixOS module system with a `m3ta.*` namespace.
+
+## Quick Start
+
+Use a template for quick setup:
+
+```bash
+# NixOS module
+nix flake init -t .#nixos-module my-module
+
+# Home Manager module
+nix flake init -t .#home-manager-module my-module
+```
+
+This copies the template into `templates/` — move it to the appropriate location and customize.
+
+## Adding a NixOS Module
+
+### 1. Create the Module File
+
+Create `modules/nixos/<my-module>.nix`:
+
+```nix
+{config, lib, pkgs, ...}:
+with lib; let
+  cfg = config.m3ta.myModule;
+in {
+  options.m3ta.myModule = {
+    enable = mkEnableOption "my module description";
+    # Add custom options here
+    someOption = mkOption {
+      type = types.str;
+      default = "default-value";
+      description = "Description of this option";
+    };
+  };
+
+  config = mkIf cfg.enable {
+    # System configuration goes here
+    environment.systemPackages = [pkgs.some-package];
+
+    # Or systemd services
+    systemd.services.my-service = {
+      enable = true;
+      description = "My service";
+      wantedBy = ["multi-user.target"];
+      serviceConfig = {
+        ExecStart = "${pkgs.some-package}/bin/some-daemon";
+      };
+    };
+  };
+}
+```
+
+### 2. Register in the Aggregator
+
+Add to `modules/nixos/default.nix`:
+
+```nix
+{
+  imports = [
+    ./ports.nix
+    ./mem0.nix
+    ./<my-module>.nix   # ← add your module
+  ];
+}
+```
+
+### 3. Export from flake.nix
+
+Add to the `nixosModules` output in `flake.nix` (optional, for direct import):
+
+```nix
+nixosModules = {
+  default = ./modules/nixos;
+  ports = ./modules/nixos/ports.nix;
+  mem0 = ./modules/nixos/mem0.nix;
+  my-module = ./modules/nixos/<my-module>.nix;  # ← add this
+};
+```
+
+## Adding a Home Manager Module
+
+Home Manager modules are organized by category under `modules/home-manager/`.
+
+### Categories
+
+| Category | Purpose | Location |
+|----------|---------|----------|
+| `cli/` | Command-line tools and utilities | `modules/home-manager/cli/` |
+| `coding/` | Development tools, editors, agents | `modules/home-manager/coding/` |
+| Root | Cross-cutting concerns (e.g., ports) | `modules/home-manager/` |
+
+### 1. Choose a Category
+
+- **CLI tools** (zsh plugins, tmux config, etc.) → `cli/`
+- **Development tools** (editor config, linters, etc.) → `coding/`
+- **System-wide settings** (ports, environment) → root level
+
+### 2. Create the Module File
+
+Create `modules/home-manager/<category>/<my-module>.nix`:
+
+```nix
+{config, lib, pkgs, ...}:
+with lib; let
+  cfg = config.m3ta.myModule;
+in {
+  options.m3ta.myModule = {
+    enable = mkEnableOption "my user module description";
+    someOption = mkOption {
+      type = types.str;
+      default = "value";
+      description = "An option for this module";
+    };
+  };
+
+  config = mkIf cfg.enable {
+    home.packages = [pkgs.some-package];
+
+    # Or Home Manager-specific options
+    programs.zsh.enable = true;
+  };
+}
+```
+
+### 3. Register in the Category Aggregator
+
+For `cli/` modules, add to `modules/home-manager/cli/default.nix`:
+
+```nix
+{
+  imports = [
+    ./rofi-project-opener.nix
+    ./stt-ptt.nix
+    ./zellij-ps.nix
+    ./<my-module>.nix   # ← add your module
+  ];
+}
+```
+
+For `coding/` modules, add to `modules/home-manager/coding/default.nix`:
+
+```nix
+{
+  imports = [
+    ./editors.nix
+    ./opencode.nix
+    ./agents
+    ./<my-module>.nix   # ← add your module
+  ];
+}
+```
+
+### 4. Export from flake.nix
+
+Add to `homeManagerModules` in `flake.nix`:
+
+```nix
+homeManagerModules = {
+  default = import ./modules/home-manager;
+  my-module = import ./modules/home-manager/<category>/<my-module>.nix;  # ← add this
+};
+```
+
+## Module Patterns
+
+### Standard Enable Option
+
+Always start with `mkEnableOption`:
+
+```nix
+options.m3ta.myModule = {
+  enable = mkEnableOption "my module";
+};
+```
+
+### Conditional Configuration
+
+Use `mkIf` for conditional config:
+
+```nix
+config = mkIf cfg.enable {
+  # Only applied when enabled
+};
+```
+
+### Multiple Conditions
+
+Use `mkMerge` when combining multiple conditional blocks:
+
+```nix
+config = mkMerge [
+  (mkIf cfg.feature1.enable { ... })
+  (mkIf cfg.feature2.enable { ... })
+];
+```
+
+### Nested Namespaces
+
+For logically grouped options, use nested namespaces:
+
+```nix
+options.m3ta.coding = {
+  myTool = {
+    enable = mkEnableOption "my coding tool";
+    # ...
+  };
+};
+```
+
+Usage: `m3ta.coding.myTool.enable = true;`
+
+### Shared Library Functions
+
+For shared utilities (port helpers, etc.), import from `lib/`:
+
+```nix
+let
+  portsLib = import ../../lib/ports.nix {inherit lib;};
+  portHelpers = portsLib.mkPortHelpers { /* ... */ };
+in {
+  # use portHelpers
+}
+```
+
+## Documentation
+
+Add documentation for your module:
+
+1. Create `docs/modules/nixos/<my-module>.md` (NixOS) or `docs/modules/home-manager/<category>/<my-module>.md` (HM)
+2. Follow the existing format in `docs/modules/`
+3. Add it to the appropriate overview page's "Available Modules" list
+4. Link it from `docs/guides/using-modules.md`
+
+## Testing
+
+```bash
+# Validate the module loads correctly
+nix flake check
+
+# Test with a minimal configuration (NixOS)
+nixos-rebuild dry-build -I nixpkgs=. --option experimental-features flakes
+
+# Format before commit
+nix fmt
+```
