Talk:Modding Tutorials/Smelter/Questions not addressed in this tutorial

First of all, I apologize if there are any errors or mistakes in this tutorial. I wrote it because it would have been immensely helpful to me if it had existed when I started out. My knowledge is far from complete and there are still a few areas unaddressed in this tutorial that should be (either here or in an advanced concepts page):

• What do Ingredients, Filter, ParentIngredientFilter, and DefaultIngredientFilter do specifically? Are they each mandatory?
• How does the value of PriorityInType work in the WorkGiverDef? Is a higher value more important or a lower value?
