I'm using Sinatra to build a site and that site will have, among other things, a blog area that I'll infrequently post articles to.

What I'd ideally like to do is have a directory of markdown files that the articles are in and to publish a new article, I'd just add a new markdown file.

The main /articles page would loop through that directory and pull the title from the markdown file's metadata.

---
title: This is my title
excerpt: This is an excerpt from the article
---

So, what I'm not sure of here is how to approach this. How would I loop through a directory of markdown files and properly display them?

FWIW, I'm using a "classic style" Sinatra app here.
