If you are familiar with docker and compose, I would start there with a servarr stack. There is a docker-compose I use called -arr-compose. Has the complete arr stack, including sabnzbd for Usenet downloads. Usenet is a bit weird, you need a server like Newshosting to actually connect to Usenet, that is what you point sabnzbd to. Prowlarr from the servarr stack connects to your indexers. Then you just search and the stack takes care of the rest. Other useful links:
Docker has an install script on their https://github.com/docker/docker-install page that takes a lot of the headache out. Also ‘sudo usermod -aG docker $USER’ will allow you to run docker without sudo.
Heading to the depot as we speak. Thank you
