The documentation tag currently has the following description:
Topics pertaining to sources for documentation and tutorials for understanding Drupal core and extension modules, using its UI (user interface), and the available code API (application programming interface) features.
I guess this is the direct opposite of
Questions asking to recommend or find a book, tool, module, theme, distribution, tutorial, or other off-site resource are off-topic for Drupal Answers as they tend to attract opinionated answers and spam. Instead, describe the problem and what has been done so far to solve it.
Most of the posts using this tag are indeed request for resources, however there are some asking how to properly document some aspects of their code.
We should at least stop encouraging people from asking these kinds of questions, so should the tag be removed, or should it be modified to explain it is supposed to be about "How to document foo in case of" type of questions? Should all the currently tagged resource requests be closed?
