It uses docker and docker-compose to orchestrate containers for the core system and apps. This repository also contains `karen`, a background daemon responsible for communication between Citadel docker containers and the Citadel Core. Citadel Core is a fully FLOSS project which replaces the previous `compose` and `compose-nonfree` repositories.
