4-month résumé gap, advice? - what worked for you?

My résumé shows a gap from a layoff and some health issues. I have done some volunteering and a course during that time. What do you say in interviews?

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.

A short, honest line such as 'family caregiving' is enough for most employers. They mostly want to know you are ready now.
