Your first tree

Make 2 crafting tables and a barrel from your first logs. Throw a crafting table and barrel on top of the other crafting table to make a crafting station.

Crafting Station

The left 3x3 grid of the crafting station is used to craft hammers, sieves and other Nothingness specific items. The 6x3 grid on the right can be used for storage. Be aware that all items in the 3x3 crafting area are consumed during crafting, even if not part of the crafting recipe. Do not use the left 3x3 for storage.

Your first hammer and sieve

Once you have some cobblestone, you can craft a hammer in the crafting station. Make a stone pickaxe pattern in the 3x3 crafting area.

Once you have some cobblestone, you can craft a sieve in the crafting station. Make a stone shovel pattern on the left side of the 3x3 crafting area.

Your first resources

You can use your hammer at your cobble gen to mine the cobble into gravel. You can then place the mined gravel and use your sieve on the gravel to obtain various resources. The list of resources that you can obtain from blocks is listed below.

Hammer and Sieve upgrades

You can craft iron, gold and diamond hammers and sieves in the crafting station. These will last longer and mine faster than the stone versions but they do not give additional resources.

Additional dirt

Combine dirt and gravel to make coarse dirt. Use a hoe on the coarse dirt to turn it into regular dirt.
Full composers will produce dirt if left full after a random period of time

Additional water

Glass bottles can fill a cauldron from you starting water source and a bucket can be filled from a full cauldron
An empty cauldron has a chance of being filled up by rain

Additional lava

If you thrown 64 cobblestone and an empty bucket in a cauldron with a heat source under it (torch, lava, fire) you will get a bucket a lava in return

Clay

4 sand and 4 dirt around a bucket of water in a crafting table makes 8 clay blocks

Grass

Throw grass seeds obtained by sieving dirt on top of dirt

Mycelium

Throw ancient spores obtained by sieving sand on top of dirt
