-## FAQ
-
-### Nextcloud Updater does not work
-It's fine, it should be. Nextcloud is updated via NixOS, and depends on our NixOS repository. Everything happens without your intervention.
-
-### Why can't I use my Nextcloud in third-party services?
-This can happen if the third-party service has a restriction to only connect to a specific Nextcloud instance.
-
-### Should I use an extension to encrypt my Nextcloud?
-We do not recommend it. The encryption keys are stored on the server, which makes such encryption practically useless.
