There is a secret that needs to be understood in order to write good software documentation: there isn’t one thing called documentation, there are four.

They are: tutorials, how-to guides, technical reference and explanation. They represent four different purposes or functions, and require four different approaches to their creation. Understanding the implications of this will help improve most documentation - often immensely.
