Just in case you wanna try again with readarr, after all the little drama and the main app being unmaintained, there’s 2 forks which are maintained and work pretty well
- Faustvii/readarr simply fixes the app to keep running
- pennydreadful/bookshelf adds a choice of metadata provider, so you can use hardcover (instead of goodreads) for really good metadata
I’ve successfully been running bookshelf for a bit now, after the original stopped working for me completely.
