This is very subtle and on the verge of picking on them. I said I'd post it when someone in class pointed it out today, so here it is. Some Revit family templates have notes to guide your first few steps. One of these is the generic tag template. When you open this one you'll see this instruction.
The instructions however are referring to the language and locations used in previous releases. The current location is the Family Properties panel and the button is called Category and Parameters. This panel shows up on all of the Family Editor Ribbons.
