 ### Request
 
 A HTTP request will be sent by a client to the [Server](#server).
-The `Server` will receive this request on the `data` event and
-is responsible to create a request object from this data.
-This object will be passed to the callback function.
- 
-The request is an instance of [PSR-7 RequestInterface](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-7-http-message.md#32-psrhttpmessagerequestinterface).
-
-As defined in PSR-7, the `getBody()` method returns a stream instance
-which implements the [PSR-7 StreamInterface](http://www.php-fig.org/psr/psr-7/#psrhttpmessagestreaminterface).
-Note that the incoming request will be processed once the request headers have
-been received, which implies that the (potentially much larger) request body
-may still be outstanding (in a streaming state).

+
+If you want to access the request body you can use `getBody()`.
+This method returns an instance that implements both the [PSR-7 StreamInterface](http://www.php-fig.org/psr/psr-7/#psrhttpmessagestreaminterface)
+and the [ReactPHP ReadableStreamInterface](https://github.com/reactphp/stream#readablestreaminterface).
+The `ReactPHP ReadableStreamInterface` implemantation
+gives you advantages like:
+
+* Receiving large amount of data without the need to buffer
+* Deny the request if the body is too big
+* Start processing parts of the body without waiting for the complete body data.
+
+Use this to receive the full potential from these scenarios and
+create a fast application.
 However, most of the `PSR-7 StreamInterface` methods have been
 designed under the assumption of being in control of the request body.
