You'll begin, as most crafters do, by gathering materials. As you run through the world, you'll have skills to triangulate gathering nodes. Upon approaching a node, you'll get to choose from a list of things you can try to gather from it -- a tree, for example, might be a place where you could find a log, or a feather, or maybe some sap. Once you've got materials, it's time to head to your crafting bench, pick a recipe, and start working. You'll have construction skills that focus on the quality and progress of your crafting.
