+In Jellyfin, create an API key from the admin dashboard, then enter the Jellyfin URL and key in the `Media` tab. If you have duplicate free/premium libraries, enter only the premium Jellyfin library names in the `Libraries` field, separated by commas. `Sync now` replaces the editable library with the current Jellyfin movies and shows while comparing against the previously saved library. `Auto-sync changes` checks Jellyfin periodically and republishes only when the catalog fingerprint changes. Jellyfin results are deduplicated across included libraries using provider IDs first, then normalized title and year.
