+# 多语言支持使用指南
+
+## 概述
+
+本项目已实现中英文双语支持，可以通过页面右上角的语言切换按钮在简体中文和英文之间切换。
+
+## 文件结构
+
+```
+static/app/
+├── i18n.js                 # 多语言配置文件（包含所有翻译）
+├── language-switcher.js    # 语言切换组件
+└── I18N_GUIDE.md          # 本指南
+```
+
+## 如何使用
+
+### 1. 在 HTML 中添加多语言支持
+
+使用 `data-i18n` 属性标记需要翻译的元素：
+
+```html
+<!-- 文本内容 -->
+<h1 data-i18n="header.title">AIClient2API 管理控制台</h1>
+
+<!-- 按钮文本 -->
+<button data-i18n="common.save">保存</button>
+
+<!-- 输入框占位符 -->
+<input type="text" data-i18n="config.apiKeyPlaceholder" placeholder="请输入API密钥">
+
+<!-- 带参数的翻译 -->
+<span data-i18n="upload.count" data-i18n-params='{"count": "10"}'>共 10 个配置文件</span>
+```
+
+### 2. 在 JavaScript 中使用翻译
+
+```javascript
+import { t } from './i18n.js';
+
+// 简单翻译
+const title = t('header.title');
+
+// 带参数的翻译
+const message = t('upload.count', { count: 10 });
+
+// 在 showToast 中使用
+showToast(t('common.success'), t('config.saved'), 'success');
+```
+
+### 3. 添加新的翻译
+
+在 `i18n.js` 文件中的 `translations` 对象中添加：
+
+```javascript
+const translations = {
+    'zh-CN': {
+        'your.key': '你的中文翻译',
+        // ...
+    },
+    'en-US': {
+        'your.key': 'Your English translation',
+        // ...
+    }
+};
+```
+
+### 4. 动态内容的翻译
+
+对于动态生成的内容，在创建 DOM 元素时添加 `data-i18n` 属性：
+
+```javascript
+const element = document.createElement('div');
+element.setAttribute('data-i18n', 'your.translation.key');
+element.textContent = t('your.translation.key');
+```
+
+## 翻译键命名规范
+
+使用点号分隔的层级结构：
+
+- `header.*` - 页头相关
+- `nav.*` - 导航相关
+- `dashboard.*` - 仪表盘相关
+- `config.*` - 配置相关
+- `providers.*` - 提供商相关
+- `upload.*` - 上传配置相关
+- `usage.*` - 用量查询相关
+- `logs.*` - 日志相关
+- `common.*` - 通用文本
+
+## 已实现的功能
+
+✅ 自动检测并保存用户语言偏好
+✅ 页面刷新后保持语言选择
+✅ 动态添加的元素自动翻译
+✅ 支持带参数的翻译
+✅ 语言切换时实时更新所有文本
+
+## 待完善的部分
+
+由于页面内容较多，以下部分需要继续添加 `data-i18n` 属性：
+
+1. 配置管理页面的表单标签和提示
+2. 提供商池管理的详细信息
+3. 上传配置管理的列表项
+4. 用量查询的统计信息
+5. 实时日志的控制按钮
+
+## 示例：完整的多语言表单
+
+```html
+<div class="form-group">
+    <label data-i18n="config.apiKey">API密钥</label>
+    <input 
+        type="password" 
+        id="apiKey" 
+        class="form-control" 
+        data-i18n="config.apiKeyPlaceholder"
+        placeholder="请输入API密钥"
+    >
+</div>
+```
+
+对应的翻译配置：
+
+```javascript
+'zh-CN': {
+    'config.apiKey': 'API密钥',
+    'config.apiKeyPlaceholder': '请输入API密钥'
+},
+'en-US': {
+    'config.apiKey': 'API Key',
+    'config.apiKeyPlaceholder': 'Please enter API key'
+}
+```
+
+## 注意事项
+
+1. 所有翻译键必须在两种语言中都存在
+2. 参数化翻译使用 `{paramName}` 格式
+3. HTML 内容使用 `data-i18n-html` 属性
+4. 语言切换会触发 `languageChanged` 事件
+5. 新添加的 DOM 元素会自动被翻译系统检测
+
+## 调试
+
+在浏览器控制台中：
+
+```javascript
+// 获取当前语言
+import { getCurrentLanguage } from './app/i18n.js';
+console.log(getCurrentLanguage());
+
+// 手动切换语言
+import { setLanguage } from './app/i18n.js';
+setLanguage('en-US');
