 Documentation is not just for beginners: it's a code companion. One never stops reading. Even experienced programmers must refer to docs when first encountering a software, and return to the references when they need a refresher on the syntax of a particular command. They continuously look at code from multiple distances: close to the source code through lines of comment—ignored by the machine, but much appreciated by fellows developers—or from printed books, along with pages of explanations and use cases.

 His framework is built at the intersection of two axis: one goes from theoretical to practical knowledges, while the other from study to work. Here _study_ could be read as _learning_ or _understanding_, while _working_ means getting things done. Another powerful couple of synonims is _receiving_ and _giving_: by combining the renamed axis we can get a glimpse of the flow of knoweldge involved in documentation.
