Hi - I would like to contribute a link to a new course about using React with a Headless CMS. It covers common challenges when building a marketing friendly React app, including optimal SEO.

I'm referring to this page here: https://github.com/reactjs/reactjs.org/blob/master/content/community/courses.md

Please let me know your thoughts / questions. Thanks!
