+Guzzle 7 Adapter
+================
+
+An HTTPlug adapter for the `Guzzle 7 HTTP client`_. Guzzle 7 supports PSR-18
+out of the box. This adapter makes sense if you want to use HTTPlug async interface or to use
+Guzzle 7 with a library that did not upgrade to PSR-18 yet and depends on ``php-http/client-implementation``.
+
+Installation
+------------
+
+To install the Guzzle adapter, which will also install Guzzle itself (if it was
+not yet included in your project), run:
+
+.. code-block:: bash
+
+    $ composer require php-http/guzzle7-adapter
+
+Usage
+-----
+
+To create a Guzzle7 adapter you should use the `createWithConfig()` function. It will let you to pass Guzzle configuration
+to the client::
+
+    use Http\Adapter\Guzzle7\Client as GuzzleAdapter;
+
+    $config = [
+        'timeout' => 2,
+        'handler' => //...
+        // ...
+    ];
+    $adapter = GuzzleAdapter::createWithConfig($config);
+
+.. note::
+
+    If you want even more control over your Guzzle object, you may give a Guzzle client as first argument to the adapter's
+    constructor::
+
+        use GuzzleHttp\Client as GuzzleClient;
+        use Http\Adapter\Guzzle7\Client as GuzzleAdapter;
+
+        $config = ['timeout' => 5];
+        // ...
+        $guzzle = new GuzzleClient($config);
+        // ...
+        $adapter = new GuzzleAdapter($guzzle);
+
+    If you pass a Guzzle instance to the adapter, make sure to configure Guzzle to not throw exceptions on HTTP error status codes, or this adapter will violate PSR-18.
+
+And use it to send synchronous requests::
+
+    use GuzzleHttp\Psr7\Request;
+
+    $request = new Request('GET', 'http://httpbin.org');
+
+    // Returns a Psr\Http\Message\ResponseInterface
+    $response = $adapter->sendRequest($request);
+
+Or send asynchronous ones::
+
+    use GuzzleHttp\Psr7\Request;
+
+    $request = new Request('GET', 'http://httpbin.org');
+
+    // Returns a Http\Promise\Promise
+    $promise = $adapter->sendAsyncRequest(request);
