# GerbilManager — TrueNAS Custom Application
# ==============================================
# Vor dem ersten Start:
#   1. Kopiere deploy/truenas/.env.example -> deploy/truenas/.env und setze die Werte.
#   2. Lege die Dataset-Pfade auf der NAS an (pgdata, photos, backups).
#   3. docker compose -f deploy/truenas/compose.yaml up -d
#
# Zugriff: http://<NAS-IP>:${PORT:-80}
# API-Doku: http://<NAS-IP>:${PORT:-80}/scalar
