Closes #1380

Are mkdocs releases variable enough that this is needed over just pip install --no-cache-dir mkdocs as mentioned in their docs?

[oregonpillow]

Sorry i don't understand exactly what you mean and i couldn't find reference to the mkdocs "release variable"?

You could install with pip install --no-cache-dir mkdocs mkdocs-meterial or you could install using the requirements file: pip install -r requirements.txt.
I just realized that some of the requirements I had were not needed and I've just simplified it to:

mkdocs==1.6.1
mkdocs-material==9.5.49

mkdocs-material is the theme being used. I tried it without and readability is objectively worse with default mkdocs theme, which is probably why the material theme seems to be a ubiquitous choice for many mkdocs sites.
