## Background

In this lab, imagine that your team is hired by a health government agency. They would like to understand factors that predict cancer mortality rates, with the ultimate aim of identifying communities for social interventions, and of understanding which interventions are likely to have the most impact.  Your team was hired to perform an exploratory analysis to help the agency address their goals.

…looks like this on GitHub

… and this on Grip

Such metadata at the top of documents is called “front matter”, and in this case, it is “YAML front matter”.

Examples of its usage in different parts of the Web:

• Jekyll uses front matter to make metadata available to pages - https://jekyllrb.com/docs/frontmatter/
• gray-matter (Node.js) is a generic parser of front matter - https://github.com/jonschlinkert/gray-matter
• Static site generator Hugo (Go) supports YAML, TOML, JSON front matter - https://gohugo.io/content-management/front-matter/

Perhaps this feature request can be called “Render front matter like GitHub does”?

Any movement on this? Was looking for support for this too. It’s a shame that @kagof’s PR was not moved forward (even if it requires iteration)
