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

What were you trying to build?
Which example or instruction did you need but could not find?
Could you complete the task after following the documentation?
Which assumption about your environment was unclear?
What would make the example easier to adapt?

Author notes / illustrative keys where applicable:
1. Anchor the response to the task being built rather than a general opinion of the documentation.
2. Identify a missing example or step so a revision can address the reader's actual obstacle.
3. Distinguish following the instructions from reaching a useful result in the reader's environment.
4. Locate an unstated environment assumption without collecting private configuration values.
5. Find the change that would make adaptation possible; an example that runs unchanged may still fail the user's real task.
