About this project
What does Essentials add?
Essentials

Essentials expands automation and redstone in a balanced and vanilla style.
While there's full ingame documentation with Patchouli installed (strongly recommended), here's a few highlights:
• A single block chest that remembers item types for each slot
• Farmland that self-replants
• Simple and cheap item transport and sorting
• Single block redstone circuits that can do logic or math
• And more...
Essentials has no worldgen, no balance destroying features, has ingame documentation (through the Essentials Guidebook with Patchouli), and is highly configurable. It can be dropped into a modpack without issues.
