OK, there are several videos on YouTube how to start, but I will try to give you some help by typing.
Let’s start.
You spawn in the desert
You find a great stone in front of you with green letters, go read it.
Then one button must dodge, press it, then one button must kick, press it, climb the big stone. Gather stones, sticks, fiber. Fix your first tool (axe) , fix your first clothing. Open your inventory, go to attributes bar, invest your first points on grit, you will need it badly, not strength grit, now you are weak, you need to run. Open inventory again, go to feats, learn how to fix weapons, the torch and the wooden chest. Fix a weapon, a torch, bandages and a bedroll, use the torch. If you fix these now run to the water, drink.
Eat the bugs you gather from fibers.
Go out of the water in a safe place, place your bedroll, fix a campfire and place it next to your bedroll, open your map, you will have to remember the location of your bedroll and campfire, it helps, hit 2 or three trees with your axe to take wood and branches, if you need stones, the axe can gather some by hitting rocks until you fix your first pick.
Don’t gather a lot, just the necessary to fix tools and campfire. Fix a stone skinning knife (learn how to from the feats), take your sword and kill something, not an npc(human) a mob(animal, start with turtle mobs), use your axe to harvest it, you gain your first head(maybe), skin and meat. Put the meat in your campfire with wood for fuel, try to press buttons, one of it will start the fire, eat the meat you cooked, now you are lvl 6, you can learn how to fix daggers, fix the daggers, by using heavy attacks you cause bleeding, that means you still don’t need strength, raize encumbrance, agility and vitality. Go from the other side of the river. If you open the map you will see a small lake, over this small lake it has a safe place to stay and hunt for your first survival needs. Do not give points to survival or accuracy, late game builds.
Try to gather some stones with your pick, fix 4 foundations, 4 ceilings, 7 walls, one door frame and a door . Build your first box, it is necessary for the sandstorm. Fix your first wooden chest to put it inside your box and your bedroll ofcurce. You are saved, now that you managed to survive you can start how to build.
