Writing Useful Technical Notes
Writing useful technical notes
Documentation is most valuable when it captures context that the code cannot. A command shows how to perform an operation; a useful note explains when to run it, what success looks like, and which assumptions make it safe.
Begin with the reader’s goal
State the outcome near the top. Readers should know within a few lines whether the page answers their question. Then present the shortest reliable path before discussing alternatives and edge cases.
Use examples that can be copied and adapted, but explain placeholders clearly. An example that looks real while hiding an important assumption is worse than no example at all.
Keep notes alive
Review documentation alongside the behavior it describes. Small updates made during regular development are cheaper than a large cleanup after everyone has stopped trusting the docs.
A page does not need to be exhaustive to be useful. It needs a clear scope, accurate steps, and enough reasoning for the next person to make a sound decision.
