+Guzzle, PHP HTTP client and webservice framework
+================================================
+
+[![Build Status](https://secure.travis-ci.org/guzzle/guzzle.svg?branch=master)](http://travis-ci.org/guzzle/guzzle)
+
+Guzzle is a PHP HTTP client that makes it easy to send HTTP requests and
+trivial to integrate with web services.
+
+- Manages things like persistent connections, represents query strings as
+  collections, simplifies sending streaming POST requests with fields and
+  files, and abstracts away the underlying HTTP transport layer.
+- Can send both synchronous and asynchronous requests using the same interface
+  without requiring a dependency on a specific event loop.
+- Pluggable HTTP adapters allows Guzzle to integrate with any method you choose
+  for sending HTTP requests over the wire (e.g., cURL, sockets, PHP's stream
+  wrapper, non-blocking event loops like ReactPHP.
+- Guzzle makes it so that you no longer need to fool around with cURL options,
+  stream contexts, or sockets.
+
+```php
+$client = new GuzzleHttp\Client();
+$response = $client->get('http://guzzlephp.org');
+$res = $client->get('https://api.github.com/user', ['auth' =>  ['user', 'pass']]);
+echo $res->getStatusCode();
+// "200"
+echo $res->getHeader('content-type');
+// 'application/json; charset=utf8'
+echo $res->getBody();
+// {"type":"User"...'
+var_export($res->json());
+// Outputs the JSON decoded data
+
+// Send an asynchronous request.
+$req = $client->createRequest('GET', 'http://httpbin.org', ['future' => true]);
+$client->send($req)->then(function ($response) {
+    echo 'I completed! ' . $response;
+});
+```
+
+Get more information and answers with the
+[Documentation](http://guzzlephp.org/),
+[Forums](https://groups.google.com/forum/?hl=en#!forum/guzzle),
+and [Gitter](https://gitter.im/guzzle/guzzle).
+
+### Installing via Composer
+
+The recommended way to install Guzzle is through
+[Composer](http://getcomposer.org).
+
+```bash
+# Install Composer
+curl -sS https://getcomposer.org/installer | php
+```
+
+Next, run the Composer command to install the latest stable version of Guzzle:
+
+```bash
+composer.phar require guzzlehttp/guzzle
+```
+
+After installing, you need to require Composer's autoloader:
+
+```php
+require 'vendor/autoload.php';
+```
+
+### Documentation
+
+More information can be found in the online documentation at
+http://guzzlephp.org/.
