+## A note on docker
+
+Using docker is completely optional, using a virtualenv should
+work just as good, though docker is very convenient. If you
+decide not to use Docker, you can use the `Dockerfile` and
+`docker-compose.yml` as detailed step-by-step guides on how
+to start the server or tests.
+
+## Commands
+
+### Starting the server
+
+    sudo docker-compose up
+
+### Running the tests
+
+    sudo docker-compose run main ./runtests
