The instruction "Making mods with Rift" could be extended in a way that developers know how to run the client straight from the IDE.

I would suggest creating a minimal, empty project similar to Forge MDK, and inside of it, a readme with list where to change things like mod name and modid in build, config and resource-pack files; as well as list of common gradle commands. (By the way, HalfLogs could have a readme too.)
