-## Docker Based Development
-
-To run the oauth server via Docker, three steps are required:
-
-    $ docker build --rm -t mozilla/fxa_oauth_server
-    $ docker run --rm -v $PWD:/opt/fxa mozilla/fxa_oauth_server npm install
-    $ docker run --rm -v $PWD:/opt/fxa --net=host mozilla/fxa_oauth_server
-
-This method shares the codebase into the running container so that you can install npm and various modules required by package.json. It then runs FxA oauth verifier in a container, while allowing you to use your IDE of choice from your normal desktop environment to develop code.
