There are plenty of resources online, but to get started I would go the easy route that I went and use docker.

Look to set up an “arr” stack. Make sure you have it set up gluetun and link to a VPN.

Essentially, you’ll buy a VPN connectio. Ensure this has P2P and Port Forwarding support.

You then set up docker in a way that first connects the vpn. If the vpn doesn’t work then it won’t start the download client like qbittorrent.

If you wait until after work I can share my docker compose file to give you an idea, but honestly if you’re somewhat capable with a keyboard then you can google you’re way to getting set up.
