@mikehardy sorry if there's someone else I should ping, but you're the only maintainer I'm familiar with (thanks for all you do!)

Indeed - this one is queued for review, just dormant a bit - thanks for your patience

[mikehardy]

This became quite the odyssey 😅 - we're in the process of a major refactor of the repository and part of it was fully overhauling the docs - your PR still had merit though, even in the overhauled docs site we still had this as part of our navigation bar - I've updated the PR to match current docs site (along with a commit that fixes a few leftover files from the conversion I did), and it should be good to go

Thanks again
