Suggested Improvement

add a sentence about the default behavior of the rejected status code.

"the default behavior is to reject every response that returns with a status code that falls out of the range of 2xx and treat it as an error."

and make a small addition to the validateStatus header, to explain what the default condition.

Using the validateStatus config option, you can override the default condition (status >= 200 && status < 300) and define HTTP code(s) that should throw an error.
