-# CC Switch 国际化功能说明
-
-## 已完成的工作
-
-1. **安装依赖**：添加了 `react-i18next` 和 `i18next` 包
-2. **配置国际化**：在 `src/i18n/` 目录下创建了配置文件
-3. **翻译文件**：创建了英文、中文、日文翻译文件
-4. **组件更新**：替换了主要组件中的硬编码文案
-5. **语言切换器**：添加了语言切换按钮
-
-## 文件结构
-
-```
-src/
-├── i18n/
-│   ├── index.ts          # 国际化配置文件
-│   └── locales/
-│       ├── en.json       # 英文翻译
-│       ├── ja.json       # 日文翻译
-│       └── zh.json       # 中文翻译
-├── components/
-│   └── LanguageSwitcher.tsx  # 语言切换组件
-└── main.tsx              # 导入国际化配置
-```
-
-## 默认语言设置
-
- **默认语言**：中文 (zh)（无首选时根据浏览器/系统语言选择 zh/en/ja）
- **回退语言**：英文 (en)
-
-## 使用方式
-
-1. 在组件中导入 `useTranslation`：
-   ```tsx
-   import { useTranslation } from 'react-i18next';
-
-   function MyComponent() {
-     const { t } = useTranslation();
-     return <div>{t('common.save')}</div>;
-   }
-   ```
-
-2. 切换语言：
-   ```tsx
-   const { i18n } = useTranslation();
-   i18n.changeLanguage('zh'); // 切换到中文
-   ```
-
-## 翻译键结构
-
- `common.*` - 通用文案（保存、取消、设置等）
- `header.*` - 头部相关文案
- `provider.*` - 供应商相关文案
- `notifications.*` - 通知消息
- `settings.*` - 设置页面文案
- `apps.*` - 应用名称
- `console.*` - 控制台日志信息
-
-## 测试功能
-
-应用已添加了语言切换按钮，支持中文、英文、日文三种语言切换，验证国际化功能是否正常工作。
-
-## 已更新的组件
-
- ✅ App.tsx - 主应用组件
- ✅ ConfirmDialog.tsx - 确认对话框
- ✅ AddProviderModal.tsx - 添加供应商弹窗
- ✅ EditProviderModal.tsx - 编辑供应商弹窗
- ✅ ProviderList.tsx - 供应商列表
- ✅ LanguageSwitcher.tsx - 语言切换器
- ✅ settings/SettingsDialog.tsx - 设置对话框
-
-## 注意事项
-
-1. 所有新的文案都应该添加到翻译文件中，而不是硬编码
-2. 翻译键名应该有意义且结构化
-3. 可以通过修改 `src/i18n/index.ts` 中的 `lng` 配置来更改默认语言
