 .. note::
-    Tutor is compatible with the ``docker compose`` subcommand. However, this support is still in beta and we're not sure it will behave the same as the previous ``docker-compose`` command. So ``docker-compose`` will be preferred, unless you set an environment variable ``TUTOR_USE_COMPOSE_SUBCOMMAND`` to enforce using ``docker compose``.
