-Upgrading
-=========
-
-The technique for upgrading ``docker`` to a newer version depends on
-how you installed ``docker``.
-
-.. versionadded:: 0.5.3
-   You may wish to add a ``docker`` group to your system to avoid using sudo with ``docker``. (see :ref:`dockergroup`)
-
-
-After ``apt-get``
------------------
-
-If you installed Docker using ``apt-get`` or Vagrant, then you should
-use ``apt-get`` to upgrade.
-
-.. versionadded:: 0.6
-   Add Docker repository information to your system first.
-
-.. code-block:: bash
-
-   # Add the Docker repository key to your local keychain
-   sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 36A1D7869245C8950F966E92D8576A8BA88D21E9
-
-   # Add the Docker repository to your apt sources list.
-   sudo sh -c "echo deb https://get.docker.io/ubuntu docker main > /etc/apt/sources.list.d/docker.list"
-
-   # update your sources list
-   sudo apt-get update
-
-   # install the latest
-   sudo apt-get install lxc-docker
-
-
-After manual installation
--------------------------
-
-If you installed the Docker :ref:`binaries` then follow these steps:
-
-
-.. code-block:: bash
-
-   # kill the running docker daemon
-   killall docker
-
-
-.. code-block:: bash
-
-   # get the latest binary
-   wget http://get.docker.io/builds/Linux/x86_64/docker-latest -O docker
-   
-   # make it executable
-   chmod +x docker
-
-
-Start docker in daemon mode (``-d``) and disconnect, running the
-daemon in the background (``&``). Starting as ``./docker`` guarantees
-to run the version in your current directory rather than a version
-which might reside in your path.
-
-.. code-block:: bash
-
-   # start the new version
-   sudo ./docker -d &
-
-
-Alternatively you can replace the docker binary in ``/usr/local/bin``.
