The setup and instructions helped a lot with setting up. My library is small and local now but the future is bright. Thank you all for writing info answers and docs.
Special thanks for all the devs of Sonarr, Radarr, Prowlarr, Torrent clients and nzb360.
Extra special thanks to the devs at Jellyfin. Honestly this whole set blew my mind.

See the other reply I linked to for the tools. In those tools you define what torrent sites you want to download from and if set up correctly it should do the torrent searching and downloading for you.
Download a torrent file and put it into a torrent client. Let the client download the torrent. Take the resulting file and watch it using the video player of your choice.
