typos, format, linting

[Alexdelia]

don't hesitate to disagree with my suggestion

with that said, I would like to inform you that I only followed official markdown guideline for format and linting

I strongly recommend that you format your code

on pretty much any IDE there is an option to format on save and define custom format rules if wanted

finally, you have a lot of format error in your nix files. I recommend using alejandra to format your nix code (just do alejandra . after install)

if wanted, I can create another PR with the nix format update
