+Running Mesa in Docker
+------------------------
+
+You can run Mesa in a Docker container in a few ways.
+
+If you are a Mesa developer, first `install docker-compose <https://docs.docker.com/compose/install/>`_ and then run:
+
+.. code-block:: bash
+
+    $ docker-compose build --pull
+    ...
+    $ docker-compose up -d dev # start the docker container
+    $ docker-compose exec dev bash # enter the docker container that has your current version of Mesa installed at /opt/mesa
+    $ mesa runserver examples/Schelling # or any other example model in examples
+
+
+The docker-compose file does two important things: 
+
+* It binds the docker container's port 8521 to your host system's port 8521 so you can interact with the running model as usual by visiting localhost:8521 on your browser
+* It mounts the mesa root directory (relative to the docker-compose.yml file) into /opt/mesa and runs pip install -e on that directory so your changes to mesa should be reflected in the running container.
+
+
+If you are a model developer that wants to run Mesa on a model (assuming you are currently in your top-level model
+directory with the run.py file):
+
+.. code-block:: bash
+
+    $ docker run --rm -it -p127.0.0.1:8521:8521 -v${PWD}:/code comses/mesa:dev mesa runserver /code
