Help with a resume for my cousin?

I have a cousin who I’m helping out. He’s living with me until he’s back on his feet again. I’m trying to help him build a resume to get a new job. He’s an Ex Con, and as a result he’s had 10 years of unemployment, and I’m not sure how to explain that gap on a resume.

I’m letting him stay at my place, helping him get a car, just got his license reinstated, and he’s testing for his drivers license next week.

What advice can you share?
