Documentation
I started writing something that I thought nimx could help me out with, but the documentation is pretty sparse. I'm having to switch gears to use https://pysimplegui.readthedocs.io/en/latest/ since I'm on a time crunch, but I suspect the amount of content in this library is comparable to that. At least my Nim code should somewhat carry over to Python, but I really wanted to use Nim. I also ran into last-minute snafus like grabbing copies of SDL2.dll manually just to get it to work; someone not aware of that wouldn't even know how to look for it.

**Goal for this issue:** how to get the documentation for this library, to be more like other well-versed GUI libraries in similar languages?
