I created Slidesdown, a zero installation presentation tool, that just takes a link to a public Markdown file and creates a beautiful presentation out of it.
In version v0.2.0 hot-reloading and offline support were added as well as a small shell script for serving presentations from the local hard-drive.
The example presentation can be found here: https://slidesdown.e-jc.de/
One particular use case I have in mind is to allow software maintainers to pitch / show case their projects by creating a SLIDES.md file that lives right alongside README.md. A direct link can be generated via https://slidesdown.e-jc.de/loader.html and shared on GitHub and beyond.
I'd love to hear your feedback. Would you be interested in adding a SLIDES.md file?
