-We recommend using ESEngine CLI to quickly create a complete game server project:
+You can define your own protocol using `@esengine/rpc`:

-```bash
-mkdir my-game-server && cd my-game-server
-npm init -y
-npx @esengine/cli init -p nodejs
-```
+```typescript
+import { rpc } from '@esengine/rpc';

-Generated project structure:
+// Define custom protocol
+export const myProtocol = rpc.define({
+    api: {
+        login: rpc.api<{ username: string }, { token: string }>(),
+        getData: rpc.api<{ id: number }, { data: object }>(),
+    },
+    msg: {
+        chat: rpc.msg<{ from: string; text: string }>(),
+        notification: rpc.msg<{ type: string; content: string }>(),
+    },
+});

+title: "RPC Library"
+description: "Type-safe WebSocket RPC communication library"
+---
+
+`@esengine/rpc` is a lightweight, type-safe RPC (Remote Procedure Call) library designed for games and real-time applications.
+
+## Features
+
+- **Type-Safe**: Complete TypeScript type inference for API calls and message handling
+- **Bidirectional**: Supports both request-response (API) and publish-subscribe (message) patterns
+- **Flexible Codecs**: Built-in JSON and MessagePack codecs
+- **Cross-Platform**: Works in browsers, Node.js, and WeChat Mini Games
+
+## Installation
+
+```bash
+npm install @esengine/rpc
+```
+
+## Quick Start
+
+### 1. Define Protocol
+
+```typescript
+import { rpc } from '@esengine/rpc';
+
+// Define protocol (shared between client and server)
+export const chatProtocol = rpc.define({
+    api: {
+        // Request-response APIs
+        login: rpc.api<{ username: string }, { userId: string; token: string }>(),
+        sendMessage: rpc.api<{ text: string }, { messageId: string }>(),
+    },
+    msg: {
+        // One-way messages (publish-subscribe)
+        newMessage: rpc.msg<{ from: string; text: string; time: number }>(),
+        userJoined: rpc.msg<{ username: string }>(),
+        userLeft: rpc.msg<{ username: string }>(),
+    },
+});
+
+export type ChatProtocol = typeof chatProtocol;
+```
+
+### 2. Create Client
+
+```typescript
+import { RpcClient } from '@esengine/rpc/client';
+import { chatProtocol } from './protocol';
+
+// Create client
+const client = new RpcClient(chatProtocol, 'ws://localhost:3000', {
+    onConnect: () => console.log('Connected'),
+    onDisconnect: (reason) => console.log('Disconnected:', reason),
+    onError: (error) => console.error('Error:', error),
+});
+
+// Connect to server
+await client.connect();
+
+// Call API (type-safe)
+const { userId, token } = await client.call('login', { username: 'player1' });
+console.log('Logged in:', userId);
+
+// Listen to messages (type-safe)
+client.on('newMessage', (data) => {
+    console.log(`${data.from}: ${data.text}`);
+});
+
+// Send message
+await client.call('sendMessage', { text: 'Hello!' });
+```
+
+### 3. Create Server
+
+```typescript
+import { RpcServer } from '@esengine/rpc/server';
+import { chatProtocol } from './protocol';
+
+// Create server
+const server = new RpcServer(chatProtocol, {
+    port: 3000,
+    onStart: (port) => console.log(`Server started: ws://localhost:${port}`),
+});
+
+// Register API handlers
+server.handle('login', async (input, ctx) => {
+    const userId = generateUserId();
+    const token = generateToken();
+
+    // Broadcast user joined
+    server.broadcast('userJoined', { username: input.username });
+
+    return { userId, token };
+});
+
+server.handle('sendMessage', async (input, ctx) => {
+    const messageId = generateMessageId();
+
+    // Broadcast new message
+    server.broadcast('newMessage', {
+        from: ctx.clientId,
+        text: input.text,
+        time: Date.now(),
+    });
+
+    return { messageId };
+});
+
+// Start server
+await server.start();
+```
+
+## Core Concepts
+
+### Protocol Definition
+
+A protocol is the contract between client and server:
+
+```typescript
+const protocol = rpc.define({
+    api: {
+        // API: Request-response pattern, client initiates, server handles and returns
+        methodName: rpc.api<InputType, OutputType>(),
+    },
+    msg: {
+        // Message: Publish-subscribe pattern, either side can send, other side listens
+        messageName: rpc.msg<DataType>(),
+    },
+});
+```
+
+### API vs Messages
+
+| Feature | API | Message |
+|---------|-----|---------|
+| Pattern | Request-Response | Publish-Subscribe |
+| Return Value | Yes (Promise) | No |
+| Confirmation | Waits for response | Fire-and-forget |
+| Use Cases | Login, queries, operations | Real-time notifications, state sync |
+
+## Codecs
+
+Two built-in codecs are available:
+
+```typescript
+import { json, msgpack } from '@esengine/rpc/codec';
+
+// JSON (default, human-readable)
+const client = new RpcClient(protocol, url, {
+    codec: json(),
+});
+
+// MessagePack (binary, more efficient)
+const client = new RpcClient(protocol, url, {
+    codec: msgpack(),
+});
+```

+## 自定义协议

-```bash
-mkdir my-game-server && cd my-game-server
-npm init -y
-npx @esengine/cli init -p nodejs
-```
+```typescript
+import { rpc } from '@esengine/rpc';

-生成的项目结构：
+// 定义自定义协议
+export const myProtocol = rpc.define({
+    api: {
+        login: rpc.api<{ username: string }, { token: string }>(),
+        getData: rpc.api<{ id: number }, { data: object }>(),
+    },
+    msg: {
+        chat: rpc.msg<{ from: string; text: string }>(),
+        notification: rpc.msg<{ type: string; content: string }>(),
+    },
+});

+title: "RPC 通信库"
+description: "类型安全的 WebSocket RPC 通信库"
+---
+
+`@esengine/rpc` 是一个轻量级、类型安全的 RPC（远程过程调用）库，专为游戏和实时应用设计。
+
+## 特性
+
+- **类型安全**：完整的 TypeScript 类型推断，API 调用和消息处理都有类型检查
+- **双向通信**：支持请求-响应（API）和发布-订阅（消息）两种模式
+- **编解码灵活**：内置 JSON 和 MessagePack 编解码器
+- **跨平台**：支持浏览器、Node.js 和微信小游戏
+
+## 安装
+
+```bash
+npm install @esengine/rpc
+```
+
+## 快速开始
+
+### 1. 定义协议
+
+```typescript
+import { rpc } from '@esengine/rpc';
+
+// 定义协议（共享于客户端和服务器）
+export const chatProtocol = rpc.define({
+    api: {
+        // 请求-响应 API
+        login: rpc.api<{ username: string }, { userId: string; token: string }>(),
+        sendMessage: rpc.api<{ text: string }, { messageId: string }>(),
+    },
+    msg: {
+        // 单向消息（发布-订阅）
+        newMessage: rpc.msg<{ from: string; text: string; time: number }>(),
+        userJoined: rpc.msg<{ username: string }>(),
+        userLeft: rpc.msg<{ username: string }>(),
+    },
+});
+
+export type ChatProtocol = typeof chatProtocol;
+```
+
+### 2. 创建客户端
+
+```typescript
+import { RpcClient } from '@esengine/rpc/client';
+import { chatProtocol } from './protocol';
+
+// 创建客户端
+const client = new RpcClient(chatProtocol, 'ws://localhost:3000', {
+    onConnect: () => console.log('已连接'),
+    onDisconnect: (reason) => console.log('已断开:', reason),
+    onError: (error) => console.error('错误:', error),
+});
+
+// 连接服务器
+await client.connect();
+
+// 调用 API（类型安全）
+const { userId, token } = await client.call('login', { username: 'player1' });
+console.log('登录成功:', userId);
+
+// 监听消息（类型安全）
+client.on('newMessage', (data) => {
+    console.log(`${data.from}: ${data.text}`);
+});
+
+// 发送消息
+await client.call('sendMessage', { text: 'Hello!' });
+```
+
+### 3. 创建服务器
+
+```typescript
+import { RpcServer } from '@esengine/rpc/server';
+import { chatProtocol } from './protocol';
+
+// 创建服务器
+const server = new RpcServer(chatProtocol, {
+    port: 3000,
+    onStart: (port) => console.log(`服务器启动: ws://localhost:${port}`),
+});
+
+// 注册 API 处理器
+server.handle('login', async (input, ctx) => {
+    const userId = generateUserId();
+    const token = generateToken();
+
+    // 广播用户加入
+    server.broadcast('userJoined', { username: input.username });
+
+    return { userId, token };
+});
+
+server.handle('sendMessage', async (input, ctx) => {
+    const messageId = generateMessageId();
+
+    // 广播新消息
+    server.broadcast('newMessage', {
+        from: ctx.clientId,
+        text: input.text,
+        time: Date.now(),
+    });
+
+    return { messageId };
+});
+
+// 启动服务器
+await server.start();
+```
+
+## 核心概念
+
+### 协议定义
+
+协议是客户端和服务器之间通信的契约：
+
+```typescript
+const protocol = rpc.define({
+    api: {
+        // API：请求-响应模式，客户端发起，服务器处理并返回结果
+        methodName: rpc.api<InputType, OutputType>(),
+    },
+    msg: {
+        // 消息：发布-订阅模式，任意一方发送，对方监听
+        messageName: rpc.msg<DataType>(),
+    },
+});
+```
+
+### API vs 消息
+
+| 特性 | API | 消息 |
+|------|-----|------|
+| 模式 | 请求-响应 | 发布-订阅 |
+| 返回值 | 有（Promise） | 无 |
+| 确认 | 等待响应 | 发送即忘 |
+| 用途 | 登录、查询、操作 | 实时通知、状态同步 |
+
+## 编解码器
+
+内置两种编解码器：
+
+```typescript
+import { json, msgpack } from '@esengine/rpc/codec';
+
+// JSON（默认，可读性好）
+const client = new RpcClient(protocol, url, {
+    codec: json(),
+});
+
+// MessagePack（二进制，更高效）
+const client = new RpcClient(protocol, url, {
+    codec: msgpack(),
+});
+```
