+
+## Platform Support
+
+- **macOS**: 10.15+ (Catalina and later)
+- **Windows**: 10+ (WebView2 required)
+- **Linux**: Ubuntu 18.04+, Debian 10+, or equivalent (WebKit2GTK required)
+
+## Development
+
+### Prerequisites
+
+**macOS:**
+```bash
+brew install pkg-config libappindicator
+```
+
+**Windows:**
+```bash
+# WebView2 is automatically installed on Windows 10+
+# For development:
+winget install Microsoft.VisualStudio.2022.Community
+```
+
+**Linux:**
+```bash
+# Ubuntu/Debian
+sudo apt-get install -y libgtk-3-dev libwebkit2gtk-4.0-dev libappindicator3-dev
+
+# Fedora
+sudo dnf install gtk3-devel webkit2gtk4.0-devel
+```
+
+### Running in Development
+
+```bash
+# From project root
+npm run tauri:dev
+```
+
+This starts both the Vite dev server and the Tauri application.
+
+### Building for Production
+
+```bash
+# Build for current platform
+npm run tauri:build
+
+# Build for specific platform
+npm run tauri:build:macos
+npm run tauri:build:windows
+npm run tauri:build:linux
+```
+
+### Output Locations
+
+- **macOS**: `src-tauri/target/release/bundle/macos/`
+- **Windows**: `src-tauri/target/release/bundle/msi/` and `/msi/`
+- **Linux**: `src-tauri/target/release/bundle/deb/` and `/appimage/`
+
+## Features
+
+### Native Menu Bar
+
+Platform-specific menus are implemented in `src/menu.rs`:
+- File menu (New, Open, Save, etc.)
+- Edit menu (Undo, Redo, Cut, Copy, Paste)
+- View menu (Zoom, Fullscreen)
+- Window menu
+- Help menu
+
+### System Tray
+
+Implemented in `src/tray.rs`:
+- Show/Hide application
+- Quit from tray
+- Platform-specific tray icons
+
+### Auto-Updater
+
+Implemented in `src/updater.rs`:
+- Check for updates on startup
+- Periodic background checks
+- Download and install updates
+- Platform-specific installation logic
+
+### Window State Persistence
+
+- Window position and size
+- Maximized state
+- Last known state restoration
+
+## Configuration
+
+Main configuration is in `tauri.conf.json`:
+- Bundle identifiers
+- Icon paths
+- Window settings
+- Plugin configuration
+- Security settings
+
+## Testing
+
+```bash
+# Run Rust tests
+cargo test --manifest-path src-tauri/Cargo.toml
+
+# Run with logging
+RUST_LOG=debug npm run tauri:dev
+```
+
+## Debugging
+
+### Enable Debug Logging
+
+```bash
+export RUST_LOG=debug
+npm run tauri:dev
+```
+
+### View Tauri Logs
+
+- **macOS**: `~/Library/Logs/frenocorp-desktop/log.log`
+- **Windows**: `%APPDATA%/frenocorp-desktop/log.log`
+- **Linux**: `~/.cache/frenocorp-desktop/log.log`
+
+## Dependencies
+
+See `Cargo.toml` for complete list. Key dependencies:
+
+- `tauri v2` - Core framework
+- `tauri-plugin-fs` - File system access
+- `tauri-plugin-http` - HTTP requests
+- `tauri-plugin-dialog` - Native dialogs
+- `tauri-plugin-shell` - Shell commands
+- `tauri-plugin-store` - State persistence
+- `tokio` - Async runtime
+
+## CI/CD Integration
+
+The build scripts are designed for CI/CD integration:
+
+```yaml
+# Example GitHub Actions
+- name: Build macOS
+  run: npm run tauri:build:macos
+  
+- name: Build Windows  
+  run: npm run tauri:build:windows
+  
+- name: Build Linux
+  run: npm run tauri:build:linux
+```
+
+## Troubleshooting
+
+### Common Issues
+
+1. **WebView2 not found (Windows)**
+   - Install WebView2 runtime or enable auto-download
+
+2. **GTK not found (Linux)**
+   - Install libgtk-3-dev and libwebkit2gtk-4.0-dev
+
+3. **Code signing failed (macOS)**
+   - Configure signing identity in tauri.conf.json
+   - Or disable for development
+
+4. **Permission denied (Linux)**
+   - Ensure proper file permissions on build artifacts
