-# 国际化配置说明
-
-本项目使用 `react-i18next` 实现国际化支持。
-
-## 目录结构
-
-```
-pages/i18n/
-├── config.ts              # i18next 配置和初始化
-├── types.ts               # TypeScript 类型声明
-├── locales/

-│       ├── home.json
-│       └── docs.json
-└── README.md              # 本文件
-```
-
-## 使用方法
-
-### 在组件中使用
-
-```tsx
-import { useTranslation } from 'react-i18next'
-
-function MyComponent() {
-    const { t } = useTranslation('common') // 指定命名空间
-
-    return <h1>{t('header.nav_docs')}</h1>
-}
-```
-
-### 使用多个命名空间
-
-```tsx
-const { t } = useTranslation(['home', 'common'])
-
-// 使用时指定命名空间
-t('home:hero.title')
-t('common:header.nav_docs')
-```
-
-## 语言切换
-
-用户可以通过以下方式切换语言：
-
-1. **自动检测**：首次访问根据浏览器语言自动选择
-2. **手动切换**：点击页面右上角的语言切换按钮
-3. **持久化**：语言选择保存在 `localStorage` 中，刷新后保持
-
-## 添加新翻译
-
-1. 在对应的 JSON 文件中添加翻译条目（如 `zh-CN/home.json`）
-2. 在对应的英文文件中添加翻译（如 `en-US/home.json`）
-3. 在组件中使用 `t('namespace:key')` 获取翻译
-
-## TypeScript 支持
-
-`types.ts` 文件提供了类型声明，使得翻译 key 具有：
-
- 自动补全
- 编译期类型检查
- 防止拼写错误
-
-## 待完成
-
- [ ] 文档页翻译（`docs.json`）
- [ ] DocsLayout 导航结构国际化
- [ ] 404 页面国际化
