 # Alacritty Theme Synchronization
 
-Simple theme synchronization for Alacritty that automatically switches between Catppuccin light and dark themes based on your macOS system theme.
+Simple theme switching for Alacritty that allows you to switch between Catppuccin light and dark themes.
 
-**This solution uses Nix conditional configuration - no complex scripts or wrappers needed!**
+**This solution uses Nix conditional configuration with a simple script to switch themes.**
 
 ## How It Works
 
-1. The system detects your current macOS theme using `defaults read -g AppleInterfaceStyle`
-2. The theme is written to `/Users/danny/.local/share/nvim_color_scheme`
-3. Your NixOS configuration reads this file and conditionally applies:
-   - **Light theme** → Catppuccin Latte
-   - **Dark theme** → Catppuccin Mocha
-4. Alacritty gets the correct theme colors through Nix configuration
+1. The Nix configuration has a boolean variable `isLightTheme` in `home.nix`
+2. When `isLightTheme = true` → Catppuccin Latte (light theme)
+3. When `isLightTheme = false` → Catppuccin Mocha (dark theme)
+4. A script updates this variable and rebuilds the configuration
 
 ## Setup
 
-1. **Run the setup script:**
-   ```bash
-   ./scripts/setup-simple-theme-sync.sh
-   ```
+1. **The configuration is already set up!** Your Alacritty is currently using the light theme.
 
-2. **Apply the theme to Alacritty:**
+2. **To switch themes, use the script:**
    ```bash
-   home-manager switch
+   ./scripts/switch-alacritty-theme.sh light   # Switch to light theme
+   ./scripts/switch-alacritty-theme.sh dark    # Switch to dark theme
+   ./scripts/switch-alacritty-theme.sh toggle  # Toggle between themes
+   ./scripts/switch-alacritty-theme.sh status  # Show current theme
    ```
 
-That's it! Your Alacritty will now use the correct theme based on your system theme.
-
 ## Usage
 
-### Manual Theme Sync
-When you change your system theme, run:
+### Manual Theme Switching
 ```bash
-./scripts/sync-alacritty-theme.sh && home-manager switch
+# Switch to light theme
+./scripts/switch-alacritty-theme.sh light
+
+# Switch to dark theme  
+./scripts/switch-alacritty-theme.sh dark
+
+# Toggle between themes
+./scripts/switch-alacritty-theme.sh toggle
+
+# Check current theme
+./scripts/switch-alacritty-theme.sh status
 ```
 
-### Automatic Theme Switching (Optional)
-For automatic switching, you can set up a LaunchAgent:
-```bash
-cp assets/launchd/com.user.alacritty-theme-sync.plist ~/Library/LaunchAgents/
-launchctl load ~/Library/LaunchAgents/com.user.alacritty-theme-sync.plist
+### Manual Configuration
+You can also manually edit `nixos/home/danny/home.nix` and change:
+```nix
+isLightTheme = true;   # for light theme
+isLightTheme = false;  # for dark theme
 ```
+Then run: `cd nixos && sudo darwin-rebuild switch --flake .#Daniel-Macbook-Air`

 This approach:
 - ✅ Works with Spotlight/Applications folder launches
-- ✅ No shell aliases or wrapper scripts needed
+- ✅ No complex file reading or external dependencies
 - ✅ Integrates cleanly with NixOS configuration
-- ✅ Minimal complexity - just 3 simple scripts
-- ✅ Uses the same theme file as your Neovim configuration
+- ✅ Simple and reliable - just change a boolean and rebuild
+- ✅ Easy to understand and maintain
