Questions and answers on Stack Exchange (SE)
must be self-contained. The goal of SO/SE is to create repositories of questions and answers valuable to
future visitors. Questions and answers
requiring off-page resources are useless once those resources change or die. Any questions where a resource is
required to understand the question should be closed as "needs details of clarity", or other appropriate reason. Such "answers" should be deleted as NAA. Only
information (e.g. code) in the post itself is considered. A link can be used for context, but not for required information. —
