+CRUX Linux
+==========
+
+.. include:: install_header.inc
+
+.. include:: install_unofficial.inc
+
+Installing on CRUX Linux can be handled via the ports from `James Mills <http://prologic.shortcircuit.net.au/>`_:
+
+* `docker <https://bitbucket.org/prologic/ports/src/tip/docker/>`_
+
+* `docker-bin <https://bitbucket.org/prologic/ports/src/tip/docker-bin/>`_
+
+* `docker-git <https://bitbucket.org/prologic/ports/src/tip/docker-git/>`_
+
+The ``docker`` port will install the latest tagged version of Docker. 
+The ``docker-bin`` port will install the latest tagged versin of Docker from upstream built binaries.
+The ``docker-git`` package will build from the current master branch.
+
+
+Installation
+------------
+
+For the time being (*until the CRUX Docker port(s) get into the official contrib repository*) you will need to install
+`James Mills' <https://bitbucket.org/prologic/ports>`_ ports repository. You can do so via:
+
+Download the ``httpup`` file to ``/etc/ports/``:
+::
+    
+    curl -q -o - http://crux.nu/portdb/?a=getup&q=prologic > /etc/ports/prologic.httpup
+    
+
+Add ``prtdir /usr/ports/prologic`` to ``/etc/prt-get.conf``:
+::
+    
+    vim /etc/prt-get.conf
+
+    # or:
+    echo "prtdir /usr/ports/prologic" >> /etc/prt-get.conf
+    
+
+Update ports and prt-get cache:
+::
+    
+    ports -u
+    prt-get cache
+        
+
+To install (*and its dependencies*):
+::
+
+    prt-get depinst docker
+    
+
+Use ``docker-bin`` for the upstream binary or ``docker-git`` to build and install from the master branch from git.
+
+
+Kernel Requirements
+-------------------
+
+To have a working **CRUX+Docker** Host you must ensure your Kernel
+has the necessary modules enabled for LXC containers to function
+correctly and Docker Daemon to work properly.
+
+Please read the ``README.rst``:
+::
+    
+    prt-get readme docker
+    
+There is a ``test_kernel_config.sh`` script in the above ports which you can use to test your Kernel configuration:
+
+::
+    
+    cd /usr/ports/prologic/docker
+    ./test_kernel_config.sh /usr/src/linux/.config
+    
+
+Starting Docker
+---------------
+
+There is a rc script created for Docker. To start the Docker service:
+
+::
+    
+    sudo su -
+    /etc/rc.d/docker start
+    
+To start on system boot:
+
+- Edit ``/etc/rc.conf``
+- Put ``docker`` into the ``SERVICES=(...)`` array after ``net``.
