Very possible. I like how Jellyfin and Plex are like, “We’ll use your collection where it sits and try to figure out show name, season, and episode number from your filename convention!” And it mostly works.
Unfortunately when I installed Jellyfin, it put a lot of metadata in my /var partition, which was low on space. Oops on that one. So I had to shut down Jellyfin and delete the data until I get that situation resolved (that partition needs more space anyway).
