Hi and welcome to Vanguard community! For any kind of crafting you will need to get some experience through work and practice, guess like everything in life. At the beginning you can get yourself the crafting gear and after start doing the work orders because thats how Vanguard is built. You will get raw material for start or you suppose to harvest it. If you need fuel ingredient, you can just go to the crafting areas and purchase what you need from vendors. To make it quite clear what kind of crafting you will be doing depends on which class you will pick Blacksmith, Outfitter or Artificer.
