rough dev landing experience

[kosich]

Hey, guys! First of all: amazing project, I love the idea!

I was trying to give it a quick test, but alas, I couldn't find any demo page for it to get an impression of its capabilities. Also, neither the example code in README works (it has syntax problems), nor did I manage to run the /example/ code in an online playground. And there are no actual instructions on how to install/add the package to an existing project. I'm not well familiar with pixijs so I might be missing some obvious stuff here. npm i puxi.js and then import default or all from "puxi.js"? what version of pixijs is required?

It'd be cool to have some online editable demo for a quick overview and a short intro to pixi-ui installation and its concepts!

Thanks!
