+# Building MarkdownConverter with Tauri 2.x
+
+## Prerequisites
+
+1. **Node.js 18+** and npm
+2. **Rust 1.75+** — install via [rustup](https://rustup.rs/)
+
+```bash
+# Install Rust
+winget install Rust.Rustup  # Windows
+# OR
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh  # macOS/Linux
+
+# Set stable as default
+rustup default stable
+
+# Install Tauri CLI (alternative to npm package)
+cargo install tauri-cli --locked
+```
+
+## Development
+
+```bash
+# Install dependencies
+npm install
+
+# Run frontend dev server
+npm run dev
+
+# In another terminal, run Tauri dev
+npm run tauri:dev
+
+# Or use Tauri CLI directly (if installed globally via cargo)
+cargo tauri dev
+```
+
+## Production Build
+
+```bash
+# Build the frontend first
+npm run build:frontend
+
+# Then build Tauri app
+npm run tauri:build
+
+# Output:
+#   Windows: src-tauri/target/release/markdown-converter.exe
+#   Installer: dist/MarkdownConverter-Setup-4.3.0.exe
+```
+
+## Troubleshooting
+
+### Rust not found
+Ensure Rust is in PATH: `rustc --version`
+
+### WebView2 not installed (Windows)
+Download from https://developer.microsoft.com/en-us/microsoft-edge/webview2/
+
+### pandoc not found
+Pandoc must be installed and in PATH. Download from https://pandoc.org/installing.html
+
+## File Structure
+
+```
+src-tauri/
+  src/
+    main.rs        # Binary entry point
+    lib.rs         # Tauri app setup + command registration
+    commands/      # Rust commands (file, git, pdf, export, etc.)
+    menu.rs        # Native menu
+    tray.rs        # System tray
+    pdf_ops.rs     # PDF processing
+    plugin_manager.rs
+    error.rs
+  Cargo.toml
+  tauri.conf.json
+  capabilities/default.json
+  icons/
+src/
+  renderer.js     # Main renderer (updated for Tauri invoke/listen)
+  tauri-commands.js  # Tauri command bridge
+  index.html      # Main HTML (copied to dist/index.html)
+dist/
+  index.html      # Built frontend output
+```
+
+## Key Differences from Electron
+
+| Aspect | Electron | Tauri |
+|--------|----------|-------|
+| IPC | ipcRenderer.invoke() | invoke() from @tauri-apps/api |
+| Events | ipcRenderer.on() | listen() from @tauri-apps/api |
+| File access | Node.js fs module | Rust std::fs or tauri-plugin-fs |
+| Native menus | Electron Menu API | tauri menu API |
+| Settings | electron-store | tauri-plugin-store |
+| Binary size | ~150MB | ~10MB |
