I’m not very knowledgeable about this stuff either but I have my jellyfin setup on my main PC and store the movies/tvshows on external HDD. All I did was install the app(windows for now) and set the source folders and the basics(account password and such). Did not go into transcoding or any of the other stuff and besides some movie identification errors caused by wrong or similar names and subtitles with special characters I had no problems. Wanted to also try remote streaming but did not get much into it. But I’d be glad to help if I can.

I use both google mapy and Organic maps, while the organic maps do not have all the information google has, for simple trips and finding restaurants (no reviews) it’s perfect. Just simple and not cluttered maps with offline maps.
