Force Docker:Jellyfin to use existing config data on Synology

  docker, kodi, nas, synology

i previously ran jellyfin on my desktop comuputer and put a lot of work into the manual creation of collection (descriptions, folder pictures etc.). Now i want to implement jellyfin on my brandnew Synology DS220+ NAS, which is running Jellyfin on Docker. If my understanding of Docker is correct, it is running an instance of the jellyfin app. So while its running, i am not able to see the folders/files of jellyfin in my FileStation-Browser.

So my question is: How can i force Jellyfin/Docker to use the existing Jellyfin-Collection-Data from my desktopPC (which are bacically .xml files).

Thanks in advance!!
