 - `--name` Give your container a human-readable name
 - `--restart=always` Spin up the container when the daemon starts, or after it has been stopped

 ### Using Docker Compose
 
 Using Docker Compose can be useful for saving your specific config in files, without having to type out a long run command each time. Save compose config as a YAML file, and then run `docker compose up` (optionally use the `-f` flag to specify file location, if it isn't located at `./docker-compose.yml`).
