`restart: always` will cause containers to restart when the machine is rebooted or the docker process restarts. Setting this to `unless-stopped` will mean the container will restart only if the docker process/computer was rebooted without stopping the container first. Otherwise, running `docker-compose stop` and rebooting will cause the docker containers all to start again (and goodbye laptop battery!)
We might also consider `restart: on-failures` which would mean that rebooting would _not_ cause containers to start again unless requested via `docker-compose up`.
