Recently setup the *Arr stack&transmission+ JellyFin and loving it... (linux user, with always on server at home, behind a 5G unlimited connection)

I am a torrent person, dont understand usenet at the moment.

A few questions to fellow sailors:

• how do you safely and easily import your existing libraries? (Movies tv.shows books..)

• how do you manage multiple languages.in movies? Like having the movie in french and english both

• where and how to search for audiobooks? Really cant find many...

Any tips for daily usage?
