Lots of places lack full documentation

[HopeBaron]

Summary

Currently the project lacks full documentation with description and informative block tags in lots of places.

Goal

I open this issue with the intent of starting to fully document the whole project, little by little.

Motivation

Documentation is key to allow developers to explore the library on their own making it easier and faster to write better code.
