    echo './update.sh [-c|--check, --ours, --gc, --nightly, --prefetch, --skip-start, --skip-ping-check, --stable, -f|--force, -d|--dev, -h|--help]

  -c|--check           -   Check for updates and exit (exit codes => 0: update available, 3: no updates)
  --ours               -   Use merge strategy option "ours" to solve conflicts in favor of non-mailcow code (local changes over remote changes), not recommended!
  --gc                 -   Run garbage collector to delete old image tags
  --nightly            -   Switch your mailcow updates to the unstable (nightly) branch. FOR TESTING PURPOSES ONLY!!!!
  --prefetch           -   Only prefetch new images and exit (useful to prepare updates)
  --skip-start         -   Do not start mailcow after update
  --skip-ping-check    -   Skip ICMP Check to public DNS resolvers (Use it only if you´ve blocked any ICMP Connections to your mailcow machine)
  --stable             -   Switch your mailcow updates to the stable (master) branch. Default unless you changed it with --nightly.
  -f|--force           -   Force update, do not ask questions
  -d|--dev             -   Enables Developer Mode (No Checkout of update.sh for tests)
