Install notes for DonutSMP

Krypton is a Fabric client for PC Minecraft 1.21.11. It does not install from the in-game Mods menu. Use the Fabric profile, then drop the official jar into mods. If the game crashes on launch, confirm Fabric API is installed and you are not mixing 1.21.1 jars with 1.21.11.
