I've set up docfx as the new doc generator and am working on a brand new docs page. I don't have a lot of free time at the moment though.
The WIP docs are hosted with GitHub Pages here. There's some details left for the articles pages and API reference still needs a whole lot of work, but I think it's already pretty good compared to the old docs. If anyone checks it out, you can report any issues or design requests on the GitHub repo. Please don't report API page issues yet though.
