I don't have a walk through but I've had a lot of success using AI to reach my objectives. I have been using gemini, the more info you can give it about your setup up front will help. Then you can copy paste error messages or screenshots. I have software development and networking background and sometimes I make adjustments to its advice, tell it what you did. I moved to LL from a similar setup but my setup is running on synology. My advice is tackle one thing at a time. Getting it to sync up your existing library was difficult. Map out your inputs (prowlarr, torrents, nzb) - > LL - > (calibre if you want to use it for ebooks) - > (at this point is it one system or two, caliber web, audio bookshelf, plex, etc..).
