title: Where to add Waypoints "offset" option
body: <p>Beginner's question.  I am trying to add an offset option to a website using Waypoints, so that nav menu items will only highlight when that section is reached (150px from the top, as it is a 150px tall sticky menu).  I know the offset option is the way to go about this, but I can't find anywhere where it says where to actually add this option.  Please, as basic of a description as possible of how I should add this (is it in the HTML, scripts.js, or waypoints.js)?  It seems like I have added it everywhere to no avail.</p>
  
  <p>Please let me know if you need any more info or to see my code.  Thanks in advance!</p>
