Include the script tag after the jQuery and AngularJS script tag (upwards scroll requires jQuery to work)
<script type="text/javascript" src="jquery.min.js"></script>
<script type="text/javascript" src="angular.min.js"></script>
<script type="text/javascript" src="upwards-scroll.min.js"></script>
Make sure to add "upwards-scroll" as a dependency into your Angular app
angular.module('myApp', ['upwards-scroll']);
Use the directive by specifying an 'upwards-scroll' attribute on an element
<div upwards-scoll="myFunction()"></div>
