Hi! I am also slowly getting the hang of it (just set up my first NAS with truenas last weekend) but there are dozens of youtube channels focused on it. I like Serversathome and the accompanying Wiki helped me a lot. This mainly focuses on an arr stack but there is also wiki pages for immich and nextcloud. Right now I’m using cloudflare tunnels to access services (i know feeding the machine etc.). If anyone knows an alternative to cloudflare tunnels (without putting everything into the same tailscale network) I would be happy to hear about it!
