Advice from a Rebel down under
When you open the game up you'll realize it is quite similar to other survival games. You'll need to manage how warm you are, your stamina, and your food.
When making your first base, make sure you have multiple cooking pots so you can maximize your food output. I'd recommend making your base out of stone as it is the most durable out of the early game resources. Always make sure your doors are shut, if not an airlock design as I have had boars and wolves run into my base and surprise me while I was crafting. To maximize space in your base I would suggest having a second floor or as I have done, a secret first floor ;)
I'd recommend destroying all the trees around your base to avoid the chance of them destroying your walls (if made of wood) or ceilings. Which ever way you cut into the tree is where it is going to fall so always cut away from your base initially.
