Add your own skill
Your own categories
Categories of your own sit below the built-in ones and work the same way — add skills to them above, and each gets its own progress bar. The prefix is the short tag shown beside the category name, like KIT or SHP; leave it blank and one is made from the name. Removing a category also removes the skills inside it.
