One thing which I think the DirectX spec does really well is high visibility for its source. Take a look at https://microsoft.github.io/DirectX-Specs/. At the footer of every page, there is a friendly notice:

This site is open source. Improve this page.

I have personally used this reference to correct an error in the documentation. I think we might want to consider something similar for the Slang spec. If nothing else, I think we should put a link to this repo on the landing page and/or documentation page.
