+Congratulations on generating your Wails3 application! This README will guide you through the next steps to get your project up and running.
 
-## 技术栈
-- **后端**: Go + Wails v2 (桌面应用框架)
-- **前端**: Vue 3 + Arco Design + CodeMirror 6 + Pinia
-- **存储**: SQLite (GORM)
-- **本地文件服务器**: `localhost:8073`（CSS/JS 路径转换、HTML 预览）
+## Getting Started
 
-## 开发
-```bash
-wails dev
-```
+1. Navigate to your project directory in the terminal.
 
-## 更新
-- ✅ 文件服务器安全重构+编辑器增强+搜索排序+更新面板渲染
+2. To run your application in development mode, use the following command:
+
+   ```
+   wails3 dev
+   ```
+
+   This will start your application and enable hot-reloading for both frontend and backend changes.
+
+3. To build your application for production, use:
+
+   ```
+   wails3 build
+   ```
+
+   This will create a production-ready executable in the `build` directory.
+
+## Exploring Wails3 Features
+
+Now that you have your project set up, it's time to explore the features that Wails3 offers:
+
+1. **Check out the examples**: The best way to learn is by example. Visit the `examples` directory in the `v3/examples` directory to see various sample applications.
+
+2. **Run an example**: To run any of the examples, navigate to the example's directory and use:
+
+   ```
+   go run .
+   ```
+
+   Note: Some examples may be under development during the alpha phase.
+
+3. **Explore the documentation**: Visit the [Wails3 documentation](https://v3.wails.io/) for in-depth guides and API references.
+
+4. **Join the community**: Have questions or want to share your progress? Join the [Wails Discord](https://discord.gg/JDdSxwjhGf) or visit the [Wails discussions on GitHub](https://github.com/wailsapp/wails/discussions).
+
+## Project Structure
+
+Take a moment to familiarize yourself with your project structure:
+
+- `frontend/`: Contains your frontend code (HTML, CSS, JavaScript/TypeScript)
+- `main.go`: The entry point of your Go backend
+- `app.go`: Define your application structure and methods here
+- `wails.json`: Configuration file for your Wails project
+
+## Next Steps
+
+1. Modify the frontend in the `frontend/` directory to create your desired UI.
+2. Add backend functionality in `main.go`.
+3. Use `wails3 dev` to see your changes in real-time.
+4. When ready, build your application with `wails3 build`.
+
+Happy coding with Wails3! If you encounter any issues or have questions, don't hesitate to consult the documentation or reach out to the Wails community.
