Upscaling and better codec support than jellyfin

This is the best one I've seen yet. Although I used this one instead and customized it to my needs (Prowlarr instead of Jackett, arch-qBittorrentvpn instead of Transmission, etc)

Be sure to protect yourself while torrenting!

I really like YAMS. This will get you a setup based on docker that runs the *arr stack, qbittorrent, and has support for VPN out of the box. Lets you choose between Plex, emby, and jellyfin. It's also extremely easy to add sabnzbd (or whatever usenet dl client you want) by just copying a few lines in the docker compose file. It also makes updating wicked easy, just 'yams restart'.
