If you want to install install docker engine (super simple instructions on docker's website) then if you make a directory and put the compose file below in it (you can call it whatever but docker-compose.yaml is a convention choice) and create another directory in that directory named "jellyfin" the below compose file will work mostly out of the box. you just run docker compose up -d in the directory. If you named the compose file something else you just need to specify -f filenameofcompose in the run command. I included an nfs mount example you can delete if you aren't using nfs mount (the volumes: head and examplenfsmount at the bottom) or adjust it/copy it for your nas situation. If you have your media locally mounted on the computer you are doing this on you can change out the xamplenfsmount for /path to your files. you can also duplicate that line for any other paths to media on your system/nfs/etc. once it's up you just go to http://ipofthebox:8096/jellyfin in a web browser and follow the prompts. It's not too bad at all to get going. I'm out of time to check you might not need /jellyfin in the url. if the first line doesn't work try it without /jellyfin
