I just installed the Punch theme on one of my websites and the documentation talks about Skills:
You can add “Skills” for each portfolio Item. Skills are used for categorisation of the portfolio items, and the filtering on the Portfolio page. When setting up skills, it is important that you name the slugs correctly. The slug of each skill should be the same as the name, but all lowercase. If the skill name contains spaces, then these should be represented in the slug with a ‘-‘.
I don’t see a Skills section – maybe you mean Categories in the Portfolio section?
Just want to make sure I’m not missing anything.
Thanks!
