14-month résumé gap, advice? - first time posting

My résumé shows a gap from a layoff and some health issues. It has been a long 17 weeks. I have done some volunteering and a course during that time. How did you handle it on your résumé?

Keep your skills fresh and mention anything recent. It shows momentum.

I listed the volunteering and course under the same dates and kept the explanation to a sentence in the cover letter.
