Explaining a gap after caregiving or layoff after 6 years as a janitorial supervisor

My résumé shows a gap from a layoff and some health issues. I have read a lot of threads here and could not find my exact situation. I have done some volunteering and a course during that time. How did you handle it on your résumé?

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