+GatewayWorker 
+=================
+
+GatewayWorker基于[Workerman](https://github.com/walkor/Workerman)开发的一个项目框架，用于快速开发长连接应用，例如app推送服务端、即时IM服务端、游戏服务端、物联网、智能家居等等。
+
+GatewayWorker使用经典的Gateway和Worker进程模型。Gateway进程负责维持客户端连接，并转发客户端的数据给Worker进程处理；Worker进程负责处理实际的业务逻辑，并将结果推送给对应的客户端。Gateway服务和Worker服务可以分开部署在不同的服务器上，实现分布式集群。
+
+GatewayWorker提供非常方便的API，可以全局广播数据、可以向某个群体广播数据、也可以向某个特定客户端推送数据。配合Workerman的定时器，也可以定时推送数据。
+
+快速开始
+======
+开发者可以从一个简单的demo开始(demo中包含了GatewayWorker内核，以及start_gateway.php start_business.php等启动入口文件)<br>
+[点击这里下载demo](http://www.workerman.net/download/GatewayWorker.zip)。<br>
+demo说明见源码readme。
+
+手册
+=======
+http://www.workerman.net/gatewaydoc/
+
+安装内核
+=======
+
+只安装GatewayWorker内核文件（不包含start_gateway.php start_businessworker.php等启动入口文件）
+```
+composer require workerman/gateway-worker
+```
+
+使用GatewayWorker开发的项目

+
+## What is it
+Workerman is an asynchronous event-driven PHP framework with high performance to build fast and scalable network applications. 
+Workerman supports HTTP, Websocket, SSL and other custom protocols. 
+Workerman supports event extension.
+
+## Requires
+PHP 5.3 or Higher  
+A POSIX compatible operating system (Linux, OSX, BSD)  
+POSIX and PCNTL extensions required   
+Event extension recommended for better performance  
+
+## Installation
+
+```
+composer require workerman/workerman
+```
+
+## Basic Usage
+
+### A websocket server 
+```php
+<?php
+
+use Workerman\Worker;
+
+require_once __DIR__ . '/vendor/autoload.php';
+
+// Create a Websocket server
+$ws_worker = new Worker('websocket://0.0.0.0:2346');
+
+// 4 processes
+$ws_worker->count = 4;
+
+// Emitted when new connection come
+$ws_worker->onConnect = function ($connection) {
+    echo "New connection\n";
+};
+
+// Emitted when data received
+$ws_worker->onMessage = function ($connection, $data) {
+    // Send hello $data
+    $connection->send('Hello ' . $data);
+};
+
+// Emitted when connection closed
+$ws_worker->onClose = function ($connection) {
+    echo "Connection closed\n";
+};
+
+// Run worker
+Worker::runAll();
+```
+
+### An http server
+```php
+use Workerman\Worker;
+
+require_once __DIR__ . '/vendor/autoload.php';
