The idea here is to use reveal.js and org-mode to present stuff
- reveal.js is required
- htmlize.el (for syntax highlighting)
- obvs, ox-reveal.el package.

You can either use a CDN to deliver the reveal.js, or you can download source. Both examples are given here:
 ~(setq org-reveal-root "file:///~/Documents/projects/agares/applicationConfiguration/.emacs/src/reveal.js-3.8.0"))~
