First: get 10 wood by beating on a tree with your fist by standing in front of it and hitting the action button
Second: get 20 stone by beating on a rock with your fist by standing in front of it and hitting the action button
Third: open your crafting menu – it looks like a repair kit – find the Stone Axe option and click the craft button
Fourth: wield the axe
Fifth: find more trees and beat on them with the axe.
Repeat step 5 until you have enough wood to make walls. If you find pinecones, you can use those to make more trees, or sell them for some wood.
If you want help with something find me in discord. Do not clutter up forums.
