 ```bash

 ```
+
+
+### Using Docker
+
+A development instance of the C2 application can be spun up quickly
+using [Docker Compose](https://docs.docker.com/compose/).
+
+#### Setup
+
+1. [Install docker-compose](https://docs.docker.com/compose/install/).
+
+2. If you're using `boot2docker` (e.g., on OSX), start up `boot2docker`
+    (`boot2docker init` and then `boot2docker up`), then get the local IP address
+    of the VM with `boot2docker ip`. The output of this will be the local URL you'll
+    access. So if the IP is `192.168.59.103/`, you'll access the site locally at
+    `http://192.168.59.103:3000`.
+
+3. Update the GitHub application callback URLs to use the IP address (start
+   [here](https://github.com/settings/developers)).
+
+After setting your Github application credentials in your `.env` file as
+described above, start up the database and application server using
+`docker-compose`.
+
+#### Running
+
+It's as simple as:
+
+```
+$ docker-compose up
+```
+
+And visiting `[the IP from boot2docker IP]:5000`.
+
+The sample data will be populated in the database automatically.
+
+To run the tests:
+
+```
+$ docker-compose run web bundle exec rake spec
+```
+
+You should be able to run any Rails command by prepending it with `docker-compose run web`.
+
+
+#### Using Docker
+
+```
+docker-compose up -d
+docker-compose run web bundle exec rake spec
+```
