 Socket Client
 =============
+
+The socket client uses the stream extension from PHP, which is integrated into
+the core.
+
+Features
+--------
+
+* TCP Socket Domain (``tcp://hostname:port``)
+* UNIX Socket Domain (``unix:///path/to/socket.sock``)
+* TLS / SSL encryption
+* Client Certificate (only for PHP > 5.6)
+
+Installation
+------------
+
+To install the Socket client, run:
+
+.. code-block:: bash
+
+    $ composer require php-http/socket-client
+
+Usage
+-----
+
+The Socket client needs a :ref:`message factory <message-factory>` in order to
+to work::
+
+    use Http\Client\Socket\Client;
+
+    $options = [];
+    $client = new Client($messageFactory, $options);
+
+The available options are:
+
+:remote_socket: Specify the remote socket where the library should send the request to
+
+    * Can be a TCP remote: ``tcp://hostname:port``
+    * Can be a UNIX remote: ``unix:///path/to/remote.sock``
+    * Do not use a TLS/SSL scheme, this is handle by the SSL option.
+    * If not set, the client will try to determine it from the request URI or host header.
+:timeout: Timeout in milliseconds for writing request and reading response on the remote
+:ssl: Activate or deactivate SSL/TLS encryption
+:stream_context_options: Custom options for the context of the stream. See `PHP stream context options <http://php.net/manual/en/context.php>`_.
+:stream_context_params: Custom parameters for the context of the stream. See `PHP stream context parameters <http://php.net/manual/en/context.params.php>`_.
+:write_buffer_size: When sending the request we need to buffer the body, this option specify the size of this buffer, default is 8192,
+ if you are sending big file with your client it may be interesting to have a bigger value in order to increase performance.
+
+As an example someone may want to pass a client certificate when using the ssl, a valid configuration for this
+use case would be::
+
+    use Http\Client\Socket\Client;
+
+    $options = [
+        'stream_context_options' => [
+            'ssl' => [
+                'local_cert' => '/path/to/my/client-certificate.pem'
+            ]
+        ]
+    ];
+    $client = new Client($messageFactory, $options);
