I actually think the other resources, including WebGL fundamentals, are really great. But whenever I tried reading them, they just didn't click for me.

I don't mind organizing the code. I just want the barebones in the beginning. I see that WebGL fundamentals, for example, uses a webgl-utils library, which is what tripped me up, even though it's only used for one small utility.

Basically, I'm still on Chapter 0 :)
