Help with documentation setup

[tommyod]

If someone reading this is knowledgeable with Sphinx: I could use some help reviewing the existing setup for the Sphinx documentation and improving upon it.

Ideally, I would want:

• A clean, nice setup. No unnecessary complexity, but not bare-bones either.
• A review of the conf.py file and the existing setup structure.
• Improvement suggestions that align with the first point above.
