If nothing was unclear or difficult, say so. Skip questions about steps you did not experience; use not applicable where appropriate.

Which section helped your task?
What example was missing?
What would make the resource easier to use?

Author notes / illustrative keys where applicable:
1. Find the section the reader used for a concrete task and why it was applicable. Preserve its useful instruction without interpreting a download or positive response as qualified purchase interest.
2. A missing example identifies where the resource's guidance fails to connect to the reader's intended task. Add an appropriate illustration and scope note, rather than equating a download with successful application or purchase intent.
3. Turn the requested improvement into a testable next step. One illustrative action is: add an editable practical worksheet.
