+## Usage Examples
+
+### Minimal Neovim Setup
+
+```nix
+{config, ...}: {
+  m3ta.coding.editors = {
+    enable = true;
+    neovim.enable = true;
+  };
+}
+```
+
+### Minimal Zed Setup
+
+```nix
+{config, ...}: {
+  m3ta.coding.editors = {
+    enable = true;
+    zed.enable = true;
+  };
+}
+```
+
+### Multiple Editors
+
+```nix
+{config, ...}: {
+  m3ta.coding.editors = {
+    enable = true;
+    neovim.enable = true;
+    zed.enable = true;
+  };
+}
+```
+
+### Custom Package
+
+```nix
+{config, ...}: {
+  m3ta.coding.editors = {
+    enable = true;
+    neovim = {
+      enable = true;
+      package = pkgs.neovim-unwrapped;  # Use unwrapped version
+    };
+  };
+}
+```
+
+## Configuration Files
+
+### Neovim
+
+The module sets up Neovim configuration in:
+
+```
+~/.config/nvim/
+```
+
+You can extend it with:
+
+```nix
+{config, ...}: {
+  xdg.configFile."nvim/init.lua".text = ''
+    -- Your custom Neovim configuration
+  '';
+}
+```
+
+### Zed
+
+Zed configuration is in:
+
+```
+~/.config/zed/settings.json
+```
+
+You can customize it with:
+
+```nix
+{config, ...}: {
+  xdg.configFile."zed/settings.json".text = builtins.toJSON {
+    # Your custom Zed settings
+  };
+}
+```
+
+## Migration Guide
+
+### From Manual Configuration
+
+If you have existing editor configurations, you can:
+
+1. Backup your current config
+2. Enable the module
+3. Test it out
+4. Gradually migrate custom settings
+
+**Backup**:
+
+```bash
+# Backup Neovim
+cp -r ~/.config/nvim ~/.config/nvim.backup
+
+# Backup Zed
+cp -r ~/.config/zed ~/.config/zed.backup
+```
+
+### From Other Editors
+
+**Vim to Neovim**:
+- Most Vim configurations work with Neovim
+- Enable module and test
+- Migrate plugins to modern Lua versions
+
+**VSCode to Zed**:
+- Zed has built-in keybinding presets
+- Enable module and check keybindings
+- Adjust as needed
+
+## Keybindings
+
+### Neovim
+
+Default keybindings (Vim-style):
+
+| Mode | Key | Action |
+|-------|------|---------|
+| Normal | `i` | Enter insert mode |
+| Normal | `ESC` | Exit insert mode |
+| Normal | `:w` | Save |
+| Normal | `:q` | Quit |
+| Normal | `u` | Undo |
+| Normal | `Ctrl+r` | Redo |
+
+### Zed
+

+
+## Plugins and Extensions
+
+### Neovim
+
+The module provides a base. You can add plugins using:
+
+```nix
+{pkgs, ...}: {
+  programs.neovim.plugins = with pkgs.vimPlugins; [
+    nvim-lspconfig
+    nvim-treesitter
+    telescope-nvim
+  ];
+}
+```
+
+### Zed
+
+Zed extensions are managed through the editor:
+
+1. Open Zed
+2. Go to Extensions (Ctrl+Shift+X)
+3. Browse and install extensions
+
+## Troubleshooting
+
+### Editor Not Found
+
+Ensure the editor package is installed:
+
+```bash
+# Check Neovim
+which nvim
+
+# Check Zed
+which zed
+```
+
+### Configuration Not Applied
+
+Check if the module is enabled:
+
+```bash
+# Check Home Manager state
+home-manager show
+
+# View current config
+nix eval .#homeConfigurations.username.config.m3ta.coding.editors --apply builtins.attrNames
+```
+
+### Conflicts with Existing Config
+
+If you have existing configuration:
+
+1. Backup current config
+2. Test module with fresh config
+3. Gradually add custom settings
