You will want a download client - I prefer SABnzbd. You might want automators like sonarr, radarr. Someone will come along with a helpful start-to-finish guide for a complete automation setup. I set mine up so long ago I can’t recall what workflow I used.

get frugal usenet, install SabNZB as your downloader. download NZbs for what you want from drunkenslug, load NZB into SabNZB and it will download from the frugal servers. sometimes things are missing depending on what you are after so if that happens move on or find a repost. once you master the manual way you can set up automation with sonarr and what not.
