+======================
+Docker Remote API v1.9
+======================
+
+.. contents:: Table of Contents
+
+1. Brief introduction
+=====================
+
+- The Remote API has replaced rcli
+- The daemon listens on ``unix:///var/run/docker.sock``, but you can
+  :ref:`bind_docker`.
+- The API tends to be REST, but for some complex commands, like
+  ``attach`` or ``pull``, the HTTP connection is hijacked to transport
+  ``stdout, stdin`` and ``stderr``

+
+	**Stream details**:
+
+	When using the TTY setting is enabled in
+	:http:post:`/containers/create`, the stream is the raw data
+	from the process PTY and client's stdin.  When the TTY is
+	disabled, then the stream is multiplexed to separate stdout
+	and stderr.
+
+	The format is a **Header** and a **Payload** (frame).
+
+	**HEADER**
+
+	The header will contain the information on which stream write
+	the stream (stdout or stderr). It also contain the size of
+	the associated frame encoded on the last 4 bytes (uint32).
+
+	It is encoded on the first 8 bytes like this::
+
+	    header := [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4}
+
+	``STREAM_TYPE`` can be:
+
+	- 0: stdin (will be writen on stdout)
+	- 1: stdout
+	- 2: stderr
+
+	``SIZE1, SIZE2, SIZE3, SIZE4`` are the 4 bytes of the uint32 size encoded as big endian.
+
+	**PAYLOAD**
+
+	The payload is the raw stream.
+
+	**IMPLEMENTATION**
+
+	The simplest way to implement the Attach protocol is the following:
+
+	1) Read 8 bytes
+	2) chose stdout or stderr depending on the first byte
+	3) Extract the frame size from the last 4 byets
+	4) Read the extracted size and output it on the correct output
+	5) Goto 1)
+

+3. Going further
+================
+
+3.1 Inside 'docker run'
+-----------------------
+
+Here are the steps of 'docker run' :
+
+* Create the container
+* If the status code is 404, it means the image doesn't exists:
+        * Try to pull it
+        * Then retry to create the container
+* Start the container
+* If you are not in detached mode:
+        * Attach to the container, using logs=1 (to have stdout and stderr from the container's start) and stream=1
+* If in detached mode or only stdin is attached:
+	* Display the container's id
+
+
+3.2 Hijacking
+-------------
+
+In this version of the API, /attach, uses hijacking to transport stdin, stdout and stderr on the same socket. This might change in the future.
+
+3.3 CORS Requests
+-----------------
+
+To enable cross origin requests to the remote api add the flag "-api-enable-cors" when running docker in daemon mode.
+
+.. code-block:: bash
+
+   docker -d -H="192.168.1.9:4243" -api-enable-cors
