Upper

The Upper is the single block added by the Uppers Mod. It is the mod's only item or block, and everything the mod does revolves around it.

Players begin by crafting the Upper, then place it in the world to use it. The wiki groups the mod's content into two areas: blocks, covering the Upper itself, and processes, covering the steps players perform with it.

Because the Upper is the only block in the mod, there is no separate machine, tool, or ingredient to learn. Once you have crafted and placed an Upper, the rest of the mod consists of interacting with that block as part of its associated processes. Refer to the processes section of the wiki for the specific steps involved in using an Upper.
