I’ll keep them in mind, but I stopped using readarr because the sonarr/radarr approach didn’t work for me for books. I read individual books more than subscribe to everything an author does, and manually downloading them is not really a problem.

What problems did you have? I just put the services I wanted in a compose file, configured sonarr/radarr to use prowlarr and my torrent client and done.

Later I added lidarr and readarr but ended up removing the last one. I found it easy enough, and the modularity makes it easy to use only what you need.
