Add comments to the code.

[crgimenes]

This code started as a joke, and there are almost no comments in the code, but now I am using it as a tool to explain the state machine, and it is necessary to clarify the code and add comments so that people can study it on their own. It is necessary to follow the "godoc" standard.

I'd really appreciate it, I love this kind of stuff and am early into programming (less than a year) and I learn the most from reading other people's code. Great project btw I love it. I've been trying it out on Wayland so far
