In the same way the term “books” includes fiction, nonfiction, and biographies as genres, the term “technical documentation” includes many different content types. But what sets technical documentation apart from books are reader traits. These traits are a result of what the reader does as they read technical documentation – they use the app.

I have spent many years as an software engineer who was a total outsider to machine-learning, but with some curiosity and occasional peripheral interactions with it.
