Automated book grabbing is very hard imo. I’ve tried readarr and a bunch of other things. I settled on just manually downloading what I want and sending to kindle. There isn’t going to be a good automated setup until indexers get better for ebooks or readarr somehow adds support for irc downloads.
Honestly I’ve really enjoyed Zorin. It’s made life simple when it comes to migrating friends and family to Linux. Specifically the way they handle fonts and scaling in office programs when opening Microsoft files. It’s been easy to get my wife to get off of windows after they started bombarding her with adds on her fuckin desktop screen.
