 To rebuild use `docker-compose build` or `docker-compose up --build`.
 
+If you want to run the container in the background you can run `docker-compose up --detach`

+If you would like the docker container to _reboot upon restart_ on the host machine you can uncomment `restart: always` in the docker-compose.yml file and make sure the docker service is set to start upon bootup.

 ## Station Codes File
 
 If you need to regenerate [the station codes CSV file in this repo](https://raw.githubusercontent.com/jpsingleton/Huxley2/master/station_codes.csv) then you can do so easily with [`jq`](https://stedolan.github.io/jq/) (and `curl`) using an instance that has access to the staff API (and has been restarted recently). On Linux, you can install simply with your package manager, e.g. `sudo apt install jq` (on Ubuntu/Debian).
