I've built PresentMarkdownNow, a tool for converting Markdown files into live presentations in the browser. It's a straightforward npm package aimed at anyone who regularly uses Markdown for documentation or notes and needs an easy way to present it live - great for teaching, demos, or meetings.

Available on npm: https://www.npmjs.com/package/present-markdown-now

I made this for personal use but thought it could be useful to others.
