Recommended. A dofollow link from your own domain is the one that counts for search engines, and it's the link we check for a free listing.

[![Date Math — listed on Serverdex](https://serverdex.io/brand/badge.svg)](https://serverdex.io/server/io-github-jowendelapena-date-math?utm_source=badge)

Nice for visibility, but GitHub marks README links nofollow, so it doesn't pass authority. Use the HTML badge on your site as well.
