I just wanted to congratulate the documentation team for a very good experience. The documentation is clear, friendly and useful.
What software are you using to create the contents?
Thanks for the compliment, @joebordes! We’ve passed it along internally to the other doc team members.
To answer your question, the source content is in markdown and we use Hugo (and some custom scripts) to generate the HTML.
Very nice 
I am also enjoying the product, some impresive timings
