To compile and build the documentation site locally, download and install mkdocs. Instructions are here.
You will need the material theme. You can install that with pip install mkdocs-material. For more information on the material theme, check out their website.
You will also need the PymDown extensions. Install with pip install pymdown-extensions. For more information on the PymDown extensions, go here.
Then, clone the version of the docs you are interested in, cd to the docs root, and run mkdocs build, then mkdocs serve.
If you run in --strict mode, you will receive warnings about any broken links.
Have fun.
