I personally thought it was pretty well-written. It sticks to the details that are relevant in the moment so it doesn't detract or get bogged down, but it does let you know what other things are there so it doesn't feel limited or barebones.

This is my pet peeve. "We'll get back to that later" is almost never a useful thing to say, particularly not in writing, and it often just increments the mental burden of the reader by adding another loose end. Instead, outline the concepts you need within context and provide a "Read more" link.
