  2. Pick the Fabric loader and a Minecraft version that RC Lite (DEPRECATED) 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 #legacy-minecraft-lite, find RC Lite (DEPRECATED) in the results, and hit Download. GDLauncher pulls dependencies automatically.
