How do you document repeatable tasks today?

Before I built StepGrab, my process looked like this: take a screenshot, paste it into a doc, crop it, draw an arrow, type out the instruction. Repeat eleven times. Then three months later someone asks the same question and I can't find the doc anyway.

I'm curious how everyone else handles this, because I suspect the honest answer for a lot of people is "I don't." You explain it over a call, the other person takes notes, and then the next new hire asks the exact same thing.

No wrong answer here, and I'm not fishing for anyone to tell me my approach is better. I want to see what the actual split looks like, especially how big the "I just explain it again" group is next to the people already using a documentation tool.

If your answer is messier than the options, put it in the comments. The messy ones are the useful ones.
