Ask HN: How do you handle writing documentation for and refactoring your code?

For the stuff that didn't get done immediately on writing the code: Periodic review (e.g. the last hour/day of the day/week)? Only on looking at the code in the course of working on something that touches that code?

Please include if this is at a company/other group, and if it's the company policy or your own.

Cheers
