+2. Build the Dockerfile ::
+     
+     docker build -t moviepy -f Dockerfile .
+
+
+Steps to run the git repo unittests from docker
+------------------------------------------------
+
+Get a bash prompt in the moviepy container ::
+
+     cd tests
+     docker run -it -v `pwd`:/tests moviepy bash
+
+Run the tests ::
+  
+     cd tests
+     python test_issues.py
+
+Running your own moviepy script from docker
+--------------------------------------------
+
+Change directory to where your script is located
+
+If moviepy docker container is already running, you can connect by: ::
+
+     docker exec -it moviepy python myscript.py
+
+If the container isn't running already ::
+
+     docker run -it moviepy bash
+     python myscript.py
+
+You can also start a container and run a script in one command: ::
+
+     docker run -it -v `pwd`:/code moviepy python myscript.py
