+
+## What is it
+Workerman is an asynchronous event driven PHP framework with high performance for easily building fast, scalable network applications. Supports HTTP, Websocket, SSL and other custom protocols. Supports libevent/event extension, [HHVM](https://github.com/facebook/hhvm) , [ReactPHP](https://github.com/reactphp/react).
+
+## 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
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+
+// 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($connection)
+{
+    echo "Connection closed\n";
+};
+
+// Run worker
+Worker::runAll();
+```
+
+### An http server
+```php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+
+// #### http worker ####
+$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, $data)
+{
+    // $_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES are available
+    var_dump($_GET, $_POST, $_COOKIE, $_SESSION, $_SERVER, $_FILES);
+    // send data to client
+    $connection->send("hello world \n");
+};
+
+// run all workers
+Worker::runAll();
+```
+
+### A WebServer
+```php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\WebServer;
+use Workerman\Worker;
+
+// WebServer
+$web = new WebServer("http://0.0.0.0:80");
+
+// 4 processes
+$web->count = 4;
+
+// Set the root of domains
+$web->addRoot('www.your_domain.com', '/your/path/Web');
+$web->addRoot('www.another_domain.com', '/another/path/Web');
+// run all workers
+Worker::runAll();
+```
+
+### A tcp server
+```php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+
+// #### create socket and listen 1234 port ####
+$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 $data \n");
+};
+
+// Emitted when new connection come
+$tcp_worker->onClose = function($connection)
+{
+    echo "Connection closed\n";
+};
+
+Worker::runAll();
+```
+
+### Enable SSL
+```php
+<?php
+require_once __DIR__ . '/vendor/autoload.php';
+use Workerman\Worker;
+
+// SSL context.
+$context = array(
+    'ssl' => array(
+        'local_cert'  => '/your/path/of/server.pem',
+        'local_pk'    => '/your/path/of/server.key',
+        '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
