+### 🎯 核心架构设计
+
+#### 1. 服务层架构 (Services Layer)
+
+- **MessageService**: 核心消息管理服务，负责统一管理聊天消息、语音识别、AI 对话流程
+- **ChatSseService**: SSE 流式通信服务，处理与 AI 后端的实时对话
+- **CommandService**: 车控命令处理服务，提供车辆控制命令的回调机制
+- **TTSService**: 语音合成服务，支持中英文语音播报
+- **VoiceRecognitionService**: 语音识别服务，处理音频转文字
+
+#### 2. UI 层架构 (UI Layer)

+
+### 自定义包
+
+- **basic_intl**: 基础国际化支持包
+
+## 🚀 快速开始
+
+### 1. 添加依赖
+
+在您的 `pubspec.yaml` 文件中添加：
+
+```yaml
+dependencies:
+  ai_chat_assistant:
+    path: path/to/ai_chat_assistant
+```
+
+### 2. 权限配置
+
+#### Android 权限 (android/app/src/main/AndroidManifest.xml)
+
+```xml
+<uses-permission android:name="android.permission.RECORD_AUDIO" />
+<uses-permission android:name="android.permission.INTERNET" />
+<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
+<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
+```
+
+### 3. 基础集成
+
+```dart
+import 'package:flutter/material.dart';
+import 'package:ai_chat_assistant/app.dart';
+import 'package:ai_chat_assistant/services/message_service.dart';
+import 'package:ai_chat_assistant/enums/vehicle_command_type.dart';
+import 'package:provider/provider.dart';
+import 'package:permission_handler/permission_handler.dart';
+
+void main() async {
+  WidgetsFlutterBinding.ensureInitialized();
+
+  // 请求麦克风权限
+  if (!await Permission.microphone.isGranted) {
+    await Permission.microphone.request();
+  }
+
+  // 初始化 AI Chat Assistant，注册车控命令回调
+  ChatAssistantApp.initialize(
+    commandCallback: (VehicleCommandType type, Map<String, dynamic>? params) async {
+      // 处理车控命令的业务逻辑
+      print('收到车控命令: $type, 参数: $params');
+      
+      // 返回执行结果
+      return (true, {'message': '命令已执行'});
+    },
+  );
+
+  runApp(
+    ChangeNotifierProvider(
+      create: (_) => MessageService(),
+      child: const MyApp(),
+    ),
+  );
+}
+
+class MyApp extends StatelessWidget {
+  const MyApp({super.key});
+
+  @override
+  Widget build(BuildContext context) {
+    return MaterialApp(
+      title: 'My Car App',
+      home: const ChatAssistantApp(), // 直接使用 AI 助手
+    );
+  }
+}
+```
+
+### 4. 自定义集成
+
+如果您想在现有应用中集成聊天助手，可以使用浮动图标：
+
+```dart
+import 'package:ai_chat_assistant/widgets/floating_icon.dart';
+
+class MyHomePage extends StatelessWidget {
+  @override
+  Widget build(BuildContext context) {
+    return Scaffold(
+      body: Stack(
+        children: [
+          // 您的现有 UI
+          YourExistingWidget(),
+          
+          // AI 助手浮动图标
+          const FloatingIcon(),
+        ],
+      ),
+    );
+  }
+}
+```
+
+## 📖 示例项目

+    // 自定义深色主题
+  );
+}
+```
+
+### 资源文件
+

+
+## 📝 API 文档
+
+### MessageService
+
+核心消息管理服务：
+
+```dart
+class MessageService extends ChangeNotifier {
+  // 发送消息
+  Future<void> sendMessage(String text);
+  
+  // 开始语音识别
+  Future<void> startVoiceRecognition();
+  
+  // 停止语音识别
+  void stopVoiceRecognition();
+  
+  // 获取聊天历史
+  List<ChatMessage> get messages;
+}
+```
+
+### CommandService
+
+车控命令服务：
+
+```dart
+class CommandService {
+  // 注册命令回调
+  static void registerCallback(CommandCallback callback);
+  
+  // 执行车控命令
+  static Future<(bool, Map<String, dynamic>?)> executeCommand(
+    VehicleCommandType type, 
+    {Map<String, dynamic>? params}
+  );
+}
+```
+
+## 🐛 调试和故障排除
+
+### 常见问题
+
+1. **麦克风权限问题**
+   - 确保在 AndroidManifest.xml 中添加了录音权限
+   - 在应用启动时请求权限
+
+2. **网络连接问题**
+   - 检查网络权限配置
+   - 确认 SSE 服务端地址配置正确
+
+3. **TTS 播放问题**
+   - 检查音频播放权限
+   - 确认设备支持 TTS 功能
+
+### 日志调试
+
+启用详细日志：
+
+```dart
+// 在 main.dart 中启用调试日志
+void main() {
+  debugPrint('AI Chat Assistant 启动中...');
+  // ... 其他初始化代码
+}
+```

+A new Flutter project.
+
+## Getting Started
+
+This project is a starting point for a Flutter application.
+
+A few resources to get you started if this is your first Flutter project:
+
+- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
+- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+
+For help getting started with Flutter development, view the
+[online documentation](https://docs.flutter.dev/), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.
