Ask HN: Recommended tools for open sourcing presentations?

Hey there, I have some course materials I wrote on Google Slides, and I'm looking to open source them and encourage others to contribute to the materials. Google won't allow me to require login upon edit if I share my materials via link posting. Instead, I thought of using some sort of a framework/tools that would allow me to convert the slides into a better for format web developers. I noticed that many developers use `reveal.js` but I'm not sure if it's the right choice for me, any suggestions/insights? Thanks in advance.
