Improve the docs

I can see there's an example folder and a quick description of the library, but could you also provide a "Quick Start" section on the readme so we can get the feeling of the library a bit quicker?

Sure! If you want to suggest a pr I'd be happy to review it. Otherwise I'll try to get to this when I can.

ASICS we need to extend CustomPainter and on paint use the library's functions, then use that CustomPainter on a CustomPaint widget, am I right?

[dnfield]

Yeah that would work
