+packaging and is only available by building from source.  Docker also
+distributes pre-built binaries for docker.  It is recommended to just run
+the docker provided binaries rather then building from source:
+
+    sudo systemctl stop docker
+    sudo killall -9 docker
+    curl https://master.dockerproject.com/linux/amd64/docker-1.5.0-dev -o docker-dev
+    sudo ./docker-dev -d

 The basic starting environment will be created using `docker-compose`.
 This environment will start up the openstack services listed in the
 compose directory.
