What you end up with: a US TV channel lineup in Jellyfin, with a program guide that fills itself in every night, without you touching it again.
Who this is for: you've heard of Docker and Jellyfin but have never touched Dispatcharr. No Linux wizardry assumed. Every command is explained, and every step tells you what you should see before you continue.
Time: 30 minutes for a working setup (Quick Path), 60–90 minutes if you also build your own guide grabber (Proper Path). Most of that is waiting.
Difficulty: copy-paste. If a step ever looks wrong, stop and read the box under it — the failure modes are all covered.
