Yup, just do it! Whenever I write a new piece of docs I try to fit it into one of four categories. Whenever I find docs written by someone else and they're all over the place, I message them and say "Hey this would be much more useful as a how-to" and link to this site.

I think this idea is so common now that it is almost the standard for technical documentation at this point even if people don’t know it by that name.
