# =============================================================
#  urlshort-qr-gen – Docker Compose
#
#  Schnellstart (SQLite, nichts weiter noetig):
#      docker compose up -d --build
#      -> http://localhost:8080
#
#  Mit MariaDB statt SQLite:
#      docker compose --profile mysql up -d --build
#      (vorher in der .env DB_DRIVER=mysql und DB_HOST=db setzen)
