  # Notes:
  # - Install Memories and Recognize from the app store
  #  - They might need to be forced on with "nextcloud-occ app:enable memories", etc.
  # - Run "nextcloud-occ maintenance:repair" to fix broken paths
  # - Download ai models and maps with the commands given in the ui
  # - libtensorflow doesn't work properly through node, but recognize still works(?)
