-# React + TypeScript + Vite
+# ReadMD - 网页转Markdown
 
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+一个Chrome浏览器扩展，用于将网页内容提取并导出为Markdown文件。
 
-Currently, two official plugins are available:
+## 功能特性
 
-- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) 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
+- **自动提取**：使用Mozilla Readability算法自动识别页面主要内容
+- **手动选择**：支持选中特定区域进行提取
+- **图片处理**：保留图片URL链接（不转换为Base64）
+- **多种导出**：支持复制到剪贴板或下载为.md文件
+- **元数据**：自动提取标题、URL、描述等元信息
+- **不修改原页**：提取过程不影响原始网页内容
 
-## React Compiler
+## 技术栈
 
-The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+- React 18 + TypeScript
+- Vite + @crxjs/vite-plugin
+- Tailwind CSS
+- @mozilla/readability（内容提取）
+- Turndown（HTML转Markdown）
 
-## Expanding the ESLint configuration
+## 安装方法
 
-If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+1. 克隆项目
 
-```js
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-
-      // 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,
-
-      // Other configs...
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
+   ```bash
+   git clone <项目地址>
+   cd readmd
    ```
 
-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:
+2. 安装依赖
 
-```js
-// eslint.config.js
-import reactX from 'eslint-plugin-react-x'
-import reactDom from 'eslint-plugin-react-dom'
-
-export default defineConfig([
-  globalIgnores(['dist']),
-  {
-    files: ['**/*.{ts,tsx}'],
-    extends: [
-      // Other configs...
-      // Enable lint rules for React
-      reactX.configs['recommended-typescript'],
-      // Enable lint rules for React DOM
-      reactDom.configs.recommended,
-    ],
-    languageOptions: {
-      parserOptions: {
-        project: ['./tsconfig.node.json', './tsconfig.app.json'],
-        tsconfigRootDir: import.meta.dirname,
-      },
-      // other options...
-    },
-  },
-])
+   ```bash
+   npm install
    ```
+
+3. 构建扩展
+
+   ```bash
+   npm run build
+   ```
+
+4. 在Chrome中加载扩展
+   - 打开 `chrome://extensions/`
+   - 启用「开发者模式」
+   - 点击「加载已解压的扩展程序」
+   - 选择 `dist` 文件夹
+
+## 使用方法
+
+1. 点击浏览器工具栏中的扩展图标
+2. 点击「提取文章」自动提取页面主要内容，或选中部分内容后点击「提取选中区域」
+3. 在弹窗中预览提取结果
+4. 点击「复制到剪贴板」或「下载.md文件」导出
+
