FIRST YOU WILL WANT TO PURCHASE THE GAME FROM THE STEAM
THEN YOU INSTALL FROM YOUR "GAMES LIBRARY"
now this next part is VERY VERY VERY complicated so do not mess up
press the GREEN PLAY BUTTON if you miss the game will NOT launch correctrly.
that would result in your not being able to open the game to open your inventory to craft the crafting station you need to craft the crafting station that crafts the weapon with the crafting station.

now that you are in the game, it should launc h to the main menu!!!!?!?!?!!
if you are there click settings and then controls.
this will take you to controls. once there click keybindsings. this will alow you to change your keybindings to open you inventory to craft the crafting stations.
change the one that says inventory to something you prefer
(i would reccommend something easy to remember, like the space bar, or D)
very carefully write whatever you chose down... if messed up, things could go very very porly...
now that you have your bind, go into your game...

this is the FINAL STEP. DO NOT MESS UP AS IT CAN CAUSE MESSING UP ISSUES
once your game has finally loaded, very carefully press the button you have decided to make your inventory.(i would reccommend looking at the note from earlier to not mess this up)
now that you are inventory, you can use the last guide to craft the crafting station to craft the crafting weapon station crafting craft...!!!
