Oh, I get it now. That's the sort of thing I've previously seen in cover letters. Think of it as a way to connect your resume to the skills and job description and a space to talk up your own skills. You can always find ways that you can demonstrate having great skills in an area even if it's through charity/sports or just your everyday life. If there are areas where you think you're not very skilled then give a plan about how you're improving yourself through further training etc.
