I think that’s a big project for a first one, and unless things changed its configuration is not documented too well.

both because of the complexity, and because of security risks, it would be better to start with something local, like a home assistant, or a forgejo/gitea, a jellyfin, things like that. don’t expose them to the internet directly, that’s risky, sometimes they have security bugs. rather if you want remote access, set up a wireguard VPN server. It’s simpler than it sounds
