Hi! You can take the tutorial at the homepage, or else sign in (you can just sign up with Google), and then mess around- text to create, present, add sounds, images, etc. There are instructions on the right side of the page (shortcuts, syntax, etc.).
I mean, if you mess around with it for a little bit you'll get an idea quickly.
Essentially, it's a text-first tool for creating structured, shareable content-presentations, walkthroughs, even lightweight docs—using a Markdown-like syntax. But unlike most markdown tools, you can also embed images, audio, logic, and interaction, so it’s supposed to be more expressive/quicker.
It's broad right now. I'm trying to figure out wwhat people might actually use it for.. what features they like.. and what they hate.
