 You also will want to create a `docker-compose.override.yml` file, which can contain the port exposure for your
 containers. Those are excluded from the main compose file `docker-compose.yml` for sanity reasons. If any port is
-already in use, `docker compose` won't start and as you cannot disable the exposed port in
-the `docker-compose.override.yml` file, you would have to alter the original `docker-compose.yml`.
