We haven’t decided if and in what form this should be added. However we did just release ZIP exports which makes it very easy to download all of the source files for a presentation (HTML/CSS/JS/images). Those files could then be added to an empty repository.Govinda commented
I would love to have support for Git repos, too. This would make it possible to work on a common revealjs based presentation with and without slides.com at the same time.
I really find slides.com very promising, but I do want to version control my presentation with standard version control tools like git - which is the basic promise of revealjs - and work with other collaboratively. Without support for git repos I do not know if I will stick with slides.com in the long term - I mean it has a nice UI - but Powerpoint has that, too.
And I do not want to force every collaborator to use slides.com. A simple PR against a git repo should be sufficient to change something...
