# Requirements
To make it easier to have multiple `docker-compose.yml` without having to specify networks by hand, we use Traefik natively installed on the host, rather than the usual Docker install.
To make it easier to have multiple `docker-compose.yml` without having to specify networks by hand, we run Traefik on the host's network stack.

## Static configuration
Changing this requires a Traefik restart.
