Make a pitch deck for the project

[molefrog]

Would be super cool to make the deck in 5-10 slides about the Presa itself and use it as a project page. Check out how others do that:

• https://revealjs.com/#/1
• https://github.com/FormidableLabs/spectacle

Possible structure:

• What is Presa? Why do you need it for?
• A quick start with code example.
• Using blocks: typography, code etc.
• Additional features: clicker support, fullscreen mode.
• Spread the world: star on github widget.

We can try using Parcel (pros: no config needed, already supports everything needed) to build the deck inside demo/ (or deck or pitch you choose it) folder.
