Thanks for pointing this out. The post starts from the assumption that people have at least heard of "docs like code", because it's a widely-used term/practice in tech writing. So I was aiming at tech writers who heard the term, but lacked the knowledge to use the technique (original draft of the post was in response to a less technical tech writer asking me a ton of questions)

But perhaps I need to explain this up top, rather than hoping people will hang in there until the explanatory section.
