# Part of the modular post-install system (sourced by setup.sh).

# Can also be run standalone on any machine:
#   sudo bash mealie.sh
# (Docker must already be installed when run standalone)
#
# Ported from ubuntu-post-install-24.04-crowdsec.sh (# ---- MEALIE ----).
# Own ~/docker/mealie/ with a standalone docker-compose.yml.
