does anyone actually know how to use this app

you dont just ask for things to happen you experiment so just experiment thats how i learned petit

Not yet, and I actually have some programming experience. They need better instructions.

yea to me it just looks like a bunch of random letters and number

Maybe digging out my old basic book would help. Kinda, since this code looks different, but it probably wouldn't hurt anything. Maybe they'll be more resources out there once this things been out longer.
