+
+GatewayWorker1.0请使用[1.0版本的GatewayClient](https://github.com/walkor/GatewayClient/releases/tag/v1.0)
+
+GatewayWorker2.0.1-2.0.4请使用[2.0.4版本的GatewayClient](https://github.com/walkor/GatewayClient/releases/tag/2.0.4)
+

+GatewayWorker3.0.0-3.0.7版本请使用 [3.0.0版本的GatewayClient](https://github.com/walkor/GatewayClient/releases/tag/v3.0.0)<br>
+
+GatewayWorker3.0.8及以上版本请使用 [3.0.13版本的GatewayClient](https://github.com/walkor/GatewayClient/releases/tag/v3.0.13)<br>
+
+注意：GatewayClient3.0.0以后支持composer并加了命名空间```GatewayClient``` <br>
+
+## 安装（composer安装适用于3.0.0及以上版本）
+```
+composer require workerman/gatewayclient
+```
+
+## 使用
+```php
+// GatewayClient 3.0.0版本以后加了命名空间
+use GatewayClient\Gateway;
+
+/**
+ * === 指定registerAddress表明与哪个GatewayWorker(集群)通讯。===
+ * GatewayWorker里用Register服务来区分集群，即一个GatewayWorker(集群)只有一个Register服务，
+ * GatewayClient要与之通讯必须知道这个Register服务地址才能通讯，这个地址格式为 ip:端口 ，
+ * 其中ip为Register服务运行的ip(如果GatewayWorker是单机部署则ip就是运行GatewayWorker的服务器ip)，
+ * 端口是对应ip的服务器上start_register.php文件中监听的端口，也就是GatewayWorker启动时看到的Register的端口。
+ * GatewayClient要想推送数据给客户端，必须知道客户端位于哪个GatewayWorker(集群)，
+ * 然后去连这个GatewayWorker(集群)Register服务的 ip:端口，才能与对应GatewayWorker(集群)通讯。
+ * 这个 ip:端口 在GatewayClient一侧使用 Gateway::$registerAddress 来指定。
+ * 
+ * === 如果GatewayClient和GatewayWorker不在同一台服务器需要以下步骤 ===
+ * 1、需要设置start_gateway.php中的lanIp为实际的本机内网ip(如不在一个局域网也可以设置成外网ip)，设置完后要重启GatewayWorker
+ * 2、GatewayClient这里的Gateway::$registerAddress的ip填写填写上面步骤1lanIp所指定的ip，端口
+ * 3、需要开启GatewayWorker所在服务器的防火墙，让以下端口可以被GatewayClient所在服务器访问，
+ *    端口包括Rgister服务的端口以及start_gateway.php中lanIp与startPort指定的几个端口
+ *
+ * === 如果GatewayClient和GatewayWorker在同一台服务器 ===
+ * GatewayClient和Register服务都在一台服务器上，ip填写127.0.0.1及即可，无需其它设置。
+ **/

+
+## 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 ($connection) {
+    echo "Connection closed\n";
+};
+
+// Run worker
+Worker::runAll();
+```
+
+### An http server
+```php
+use Workerman\Worker;
+
+require_once __DIR__ . '/vendor/autoload.php';
+
+// #### http worker ####
+$http_worker = new Worker('http://0.0.0.0:2345');
+
+// 4 processes
+$http_worker->count = 4;
+
+// Emitted when data received
+$http_worker->onMessage = function ($connection, $request) {
+    //$request->get();
+    //$request->post();
+    //$request->header();
+    //$request->cookie();
+    //$requset->session();
+    //$request->uri();
+    //$request->path();
+    //$request->method();
+
+    // Send data to client
+    $connection->send("Hello World");
+};
+
+// Run all workers
+Worker::runAll();
+```
+
+### A tcp server
+```php
+use Workerman\Worker;
+
+require_once __DIR__ . '/vendor/autoload.php';
+
+// #### create socket and listen 1234 port ####
+$tcp_worker = new Worker('tcp://0.0.0.0:1234');
+
+// 4 processes
+$tcp_worker->count = 4;
+
+// Emitted when new connection come
+$tcp_worker->onConnect = function ($connection) {
+    echo "New Connection\n";
+};
+
+// Emitted when data received
+$tcp_worker->onMessage = function ($connection, $data) {
+    // Send data to client
+    $connection->send("Hello $data \n");
+};
+
+// Emitted when connection is closed
+$tcp_worker->onClose = function ($connection) {
+    echo "Connection closed\n";
+};
+
+Worker::runAll();
+```
+
+### Enable SSL
+```php
+<?php
+
+use Workerman\Worker;
+
+require_once __DIR__ . '/vendor/autoload.php';
+
+// SSL context.
+$context = array(
+    'ssl' => array(

+        'verify_peer' => false,
+    )
+);
+
+// Create a Websocket server with ssl context.
+$ws_worker = new Worker('websocket://0.0.0.0:2346', $context);
+
+// Enable SSL. WebSocket+SSL means that Secure WebSocket (wss://). 
+// The similar approaches for Https etc.
+$ws_worker->transport = 'ssl';
+
+$ws_worker->onMessage = function ($connection, $data) {
+    // Send hello $data
+    $connection->send('Hello ' . $data);
+};
+
+Worker::runAll();
+```
+
+### Custom protocol
+Protocols/MyTextProtocol.php
+```php
+
+namespace Protocols;
+

+ */

+
+// Run all workers
+Worker::runAll();
+```
+
+### Timer
+```php
+
+use Workerman\Worker;
+use Workerman\Timer;
+
+require_once __DIR__ . '/vendor/autoload.php';
+
+$task = new Worker();
+$task->onWorkerStart = function ($task) {
