In the specific example, the answer to the question was reported in the README file, and the question could have been closed as general reference, if we had those closing reason. (The request to add it as one of the closing reasons is Add "general reference" as reason to close a question.)
Similar questions that ask where is the settings page of a module, and which doesn't show any effort to find it where the settings page is, are (IMO) not welcome on Drupal Answers. If the OP would have reported that he read the README file, and didn't find where the settings page is because what reported in the file doesn't corresponds to what effectively implemented from the module, then that would be a bug in the documentation that comes with the module; it could also be a bug in the module that, for example, it is not implementing hook_menu()
correctly.
If the OP read two different documentation pages, and those pages say something that contradict each other, then it would be different, as there are many contradictory documentation pages, and a user could be confused on which page is correct. It would not be the case of the question reported as example, because if two different pages report a different URL for the module setting page, I could try first one, and then the other one to understand which is the correct URL. Still, questions about something that should be documented are not always low level questions.
