Markdown — for your README

[![FIXSIM — listed on Serverdex](https://serverdex.io/brand/badge.svg)](https://serverdex.io/server/io-github-gammathreetrading-fixsim?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.
