Yeah it reads like one to file away if I ever end up doing a lot of technical documentation. In this case, it's a guide that is aimed at an army of people (dozens? Hundreds? I don't even know, Red Hat has 19.000 employees) writing documentation as their day job. That is, I wouldn't be at all surprised if just the number of people writing documentation for RH is more than the number of engineers we have at my current employer (one of the major energy companies in the Netherlands).
