How to Direct the Reader to the Background and Terminology Section?
I personally don't like making presumptions about the reader's knowledge when I am writing.  Someone may, for example, be familiar with a term or concept but use it in a difference sense than the paper does.  This is especially true in cross-disciplinary work or when there are unsettled scientific issues in play.  I thus prefer a value-neutral statement.  

For example, a general pointer might be:


  See Section 2 for a review of the background and terminology of this work


while a pointer for a specific element might be:


  We thus conclude that this snark is frabjous (for more details on frabjous evaluation, see Section 2.4).
