+### Features
+
+- Gearboxes
+
+Gear Item: This item is used for crafting other items.
+
+Gearboxes: These blocks are activated with bones and activate adjacent blocks. They occasionally break a bone in your hand - based on the number of adjacent blocks. Each Gearbox can only touch one gear block directly at a time, but some gear blocks can be chained.

+
+Gear Trommel: This block sits underneath a trommel, and if there are items to seive, this block will activate the trommel without the need for coal.
+
+Chest Sorter: This powered block is capable of sorting attached chests. It can be linked in a row and requires the first Chest Sorter to have a chest placed on top. It is crafted using 4 gearboxes, 4 clay, and one chest, similar to TNT.
