Project setup guide
In order to setup a workspace to play around with the source code, first clone this repository using your Git client (make sure to select the correct branch, they are named by Minecraft versions; master is always the latest work in progress version).
Once you cloned the repository, import the Forge or Fabric project into your development environment. You may need to run
gradlew genIntellijRuns or
gradlew genEclipseRuns if there are no run configurations after importing the project.
