Wow, what is up with the material mkdocs theme (https://squidfunk.github.io/mkdocs-material/)? That's an extremely spiffy landing page, especially given that it's for a theme designed for a totally separate piece of software.
mkdocs-materials is underselling itself as only a theme imo. It bundles a lot of value that mkdocs is missing out of the box as plugins and tweaks, like a good client-side search, page tags, or easy support for a lot of markdown extensions (e.g. code syntax highlighting, admonitions/callouts).
From my personal experience mkdocs+mkdocs-material is like GNU+Linux.
