A simple video that explains downloading and setting up your own Spigot OR CraftBukkit server for 1.20 and above. I show 1.20 in this video, but it applies to every recent version and even future ones! By the end, you will have a working multiplayer server that you and your friends can play on for free! Yes, this video uses BuildTools, but it’s the only official way to get these. Jars from any other sources may work but may hide some nasty code.
One-line command: iex (irm spigot.tc.ht)
