This document discusses how to form questions in the present simple tense in English. It explains that yes/no questions are formed using auxiliary verbs like "do" or "does" before the subject. Wh-questions are formed using interrogative words like who, what, when, etc. and the verb is not changed. Yes/no questions with "be" don't use an auxiliary verb. Wh-questions can be subject or non-subject, and the placement of the auxiliary verb differs depending on that. Questions in the present simple can also be used to ask for general information.
