 ### $.smoothScroll
 
 * Utility method works without a selector: `$.smoothScroll()`
-* Can be used to scroll any element (not just `document.documentElement` / `document.body`)
-* Doesn't automatically fire, so you need to bind it to some other user interaction. For example:

 ## Note
 
-* The plugin's `$.fn.smoothScroll` and `$.smoothScroll` methods use the `$.fn.firstScrollable` DOM traversal method (also defined by this plugin) to determine which element is scrollable. If no elements are scrollable, these methods return a jQuery object containing an empty array, just like all of jQuery's other DOM traversal methods. Any further chained methods, therefore, will be called against no elements (which, in most cases, means that nothing will happen).
