-# React + TypeScript + Vite
+# Go Struct Mapping Visualizer
 
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+A visual web application for creating and managing mappings between Go struct fields with automatic code generation.
 
-Currently, two official plugins are available:
+## Features
 
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) for Fast Refresh
-- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+- **Visual Mapping**: Drag-and-drop interface for connecting struct fields
+- **Code Generation**: Generate Go transformation functions from visual mappings  
+- **Monaco Editor**: Built-in Go code editor with syntax highlighting
+- **Flow Diagrams**: Interactive diagrams using React Flow
+- **Transformer Nodes**: Custom transformation logic between fields
 
-## Deployment
-
-This project is automatically deployed to GitHub Pages when changes are pushed to the `main` branch. The live application is available at:
-
-https://thitiph0n.github.io/go-struct-mapping-visualizer/
-
-### Manual Deployment
+## Live Demo
 
-To deploy manually:
+🔗 **[https://thitiph0n.github.io/go-struct-mapping-visualizer/](https://thitiph0n.github.io/go-struct-mapping-visualizer/)**
 
-1. Build the project: `npm run build`
-2. The built files will be in the `dist` directory
-3. Push to the `main` branch to trigger automatic deployment
+## Development
 
-## Expanding the ESLint configuration
+```bash
+# Install dependencies
+npm install
 
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+# Start development server
+npm run dev
 
-```js
-export default tseslint.config([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
+# Build for production  
+npm run build
 
-      // Remove tseslint.configs.recommended and replace with this
-      ...tseslint.configs.recommendedTypeChecked,
-      // Alternatively, use this for stricter rules
-      ...tseslint.configs.strictTypeChecked,
-      // Optionally, add this for stylistic rules
-      ...tseslint.configs.stylisticTypeChecked,
+# Preview production build
+npm run preview
 
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
+# Lint code
+npm run lint
 ```
 
-You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+## Tech Stack
 
-```js
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'
+- **Frontend**: React 19 + TypeScript + Vite
+- **UI**: shadcn/ui components with Tailwind CSS
+- **Diagrams**: React Flow for visual mapping
+- **Editor**: Monaco Editor for Go code editing
+- **Icons**: Lucide React

-    extends: [
-      // Other configs...
-      // Enable lint rules for React
-      reactX.configs['recommended-typescript'],
-      // Enable lint rules for React DOM
