Since the consensus on [this](http://meta.superuser.com/questions/4046/are-explain-the-technology-to-me-questions-on-topic) question seems to be that at least under some circumstances "how does this work" questions are allowed, I propose that instead of burying this fact under what types of questions one is not allowed to ask, we move it to the positive, "What type of question should I ask" section.

The goal is not to broaden the scope of the FAQ, but to make it clearer.
