Install Up In The Sky in GDLauncher

Up In The Sky runs on Forge. Pick whichever your existing instance uses, or create a new one. GDLauncher installs the correct loader automatically.

Install on Forge

  1. Open GDLauncher and create a new instance (the + button on the Library page).
  2. Pick the Forge loader and a Minecraft version that Up In The Sky supports (1.21.5 are common choices).
  3. Open the new instance, go to the Addons tab, and click Add Addons.
  4. Paste the Quick Install ID #upinthesky, find Up In The Sky in the results, and hit Download. GDLauncher pulls dependencies automatically.
  5. Hit Play. That's it.

Before you install

Make sure your Minecraft version matches what Up In The Sky supports. As of the latest release, 1.21.5 are supported. Up In The Sky only runs on Forge; 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.
