A useful update says what it represents

A prototype, workflow image, or sample photo can document a moment in a project when it is presented with its date and a clear description. It should not be treated as a substitute for final specifications, fulfillment information, or a universal performance claim.

Keep questions attached to the current source

When a decision depends on a final detail, return to the current project page rather than relying on a detached image or old summary. Browse /updates/ for context, then use the project page for current information.
