We also published as part of this release some documentation for the so-called “Docs engine” which powers these new docs, which may somewhat answer this question.
https://developers.cloudflare.com/workers/docs-engine
(Note: They currently live within the Workers docs site for now but will get a proper home soon.)
With respect to the information architecture and content design, much of that is discussed in the Contributor’s Guide [1] and Docs-flavored Markdown [2] pages.
The very short version is that we borrowed many ideas from Divio’s documentation system [3], which recommend dividing your content into four distinct buckets: Tutorials, How-to Guides, Explanation, and Reference.
The layout and visual design were inspired by dozens of other docs sites we tested and studied, stealing the best ideas we could from everywhere we looked.
It’s also worth noting that the Cloudflare Workers docs have been open-sourced for over a year now [4], and these new docs (as well as the new engine which powers them) will continue to carry the same license. Contributions are welcome and we’re hopeful and excited to see further uses of the docs engine over time.
