Build a tent, you can find brahmins next to hub, to the south. Collect brahmins skins and when you have 10 of them go on some wasteland and use science on skins. Your new tent should appear. Remember you can have only one tent at the time. (At least it was ment to be so)
Tent is important part of a game. It lets you store goods and generally it is a safe place. No one can get there unless you bring him with you. And remember do not let anyone to be with you when you create a tent because he will be able to visit it later and use as his own.
