+## Creating images:
+```
+# You can create an image of a already configured and setup container. This allows you to effectively duplicate a system.
+# To do this, run the following commands
+
+$ docker ps --all #make note of your container id
+$ docker commit containerID newImageName
+
+# To run this image do the following
+$ docker run --privileged -e "DISPLAY=${DISPLAY:-:0.0}" -v /tmp/.X11-unix:/tmp/.X11-unix newImageName
