Look up "trash guides" for the *arr programs. I use Sabnzbd, Prowlarr, Sonarr, Radarr, Recyclarr, Jellyseerr, and Jellyfin. All in docker containers on their own vlan. Lemme know if you need any help.
I forgot to add, when I transitioned into usenet, the most confusing part was that you need to find 2 separate services. From what I understand 1st is access to a usenet to connect to, and 2nd is a service that knows how to crawl and search the 1st to find what you're looking for.
I could be wrong about that, but that's how understand it, and have yet to have issues with my setup.
