Any pointers for docs?

[karakanb]

This seems like a very cool project, thanks. As someone incredibly new to the domain, I was trying to play with the examples but it is very exhausting to play around without any documentation or comments in the code. I checked the source code as well, but couldn't see any comments around the variables and functions. Is there any documentation that I might have missed regarding how to use this project?

I can play around with all the variables and probably figure out how most of them work, but I was hoping to use this to inspire my brother with ray tracing, and I am afraid this might demotivate it, so if someone can point me to a simple documentation that'd be awesome.

Cheers!
