#krypton, find Krypton in the results, and hit Download. GDLauncher pulls dependencies automatically. - Hit Play. That's it.
Before you install
Make sure your Minecraft version matches what Krypton supports. As of the latest release, 26.1.2, 1.21.11, 1.20.6 are supported. Krypton only runs on Fabric; mods built for other loaders won't work. GDLauncher checks compatibility for you and won't install something incompatible with the instance you've chosen.
