Get a tent for some safe place, put it near some mine. Than mine for metal parts, alloys and gun powder. Chop some wood in mountains, scavenge for junk in ruins. Search deserts for fruits and flint. When you will be ready craft your first items and that's all. Next hunt for NPC, start with geckos for skin and brahmins for hides. Next move to more dangerous place and hunt some bandits, riders, slavers and other wasteland shit....good luck.
