Should I refer to a tutorial as a how-to or a how to? Is there a grammatical rule for this?

This question is too basic; it can be definitively and permanently answered by a single link to a standard internet reference source designed specifically to find that type of information. If this question can be reworded to fit the rules in the help center, please edit the question.
That is how it is to be written, as you mean a certain thing (the way) defined by the phrase. Without a hyphen it would not refer to the specific thing but just be a phrase.
There is a distinct difference.
