-Why ``sudo``?
--------------
+sudo and the docker Group
+-------------------------
 
 The ``docker`` daemon always runs as root, and since ``docker``
 version 0.5.2, ``docker`` binds to a Unix socket instead of a TCP
 port. By default that Unix socket is owned by the user *root*, and so,
 by default, you can access it with ``sudo``.
 
-Starting in version 0.5.3, if you create a Unix group called *docker*
-and add users to it, then the ``docker`` daemon will make the
-ownership of the Unix socket read/writable by the *docker* group when
-the daemon starts. The ``docker`` daemon must always run as root, but
-if you run the ``docker`` client as a user in the *docker* group then
-you don't need to add ``sudo`` to all the client commands.
