I’ve had to be a technical author on several occasions. I don’t mind it. In fact I kind of like some aspects of it. Like reading all the technical data on the subject at hand, then distilling it down into an easy-to-follow step-by-step format. I sometimes play around with the text, if I have time. Tweak this bit or that. Make a sentence or paragraph read better, to be more clear, or to say the same thing with less words. Concise.
It’s usually under-appreciated though. Your target audience just wants the bare facts. The how to information as fast as possible. They don’t care about how you do it, only that you have, and that anyone can follow it.
Sigh.
The joy of writing manuals.
