What it does

The mod is an unofficial expansion of ProjectE, rewritten from the ground up after the earlier ProjectEX project was largely left unmaintained, and it adds some new content of its own. Installation covers the server and each player's game. Optional support for Cloth Config API and Curios API is available.

What the author says

This is based on ProjectEX, which seems to be mostly abandoned at this point. This has been rewritten from the ground up, and has some new things. See the wiki on our github for more information about the mod.
