Give it a go, I just finished the docker with tailscale setup. Using parts of this guide from Alex from tailscale https://youtu.be/guHoZ68N3XM (for the ones saying don't post yt links, I've not seen an add in the past 6 years or so, just use revanced) 2 hickups I had to overcome: a dns issue and different gpu passthrough then jellyfin uses). Reason was unpriviliged lxc in proxmox in both cases. But I prefer an lxc in this case. Just lost 2hrs looking back at old photos, it works great! Rdy for introducing it to my non tech wife!

Pretty easy.

Yes they mean a SMB share. A type of network share that works (mostly) with Linux and windows.
