It's simple ! All you need is to add the script on your document HTML5.
                        <script src="scrollux.js"></script>
                
                
                    var scroll = new Scrollux({});
                
                options :
                    var scroll = new Scrollux({ 
                        overflowY : "hidden", 
                        overflowX : "hidden", 
                        ringListColor : "#FFF", 
                        ringListSize : "9px", 
                        ringActualSessionColor : "#FFF", 
                        ringHoverColor : "#FFF", 
                        setTimeAnimation : 1000 
                    });
                
            You can customize the animation, the buttons list, and all you need to do is to add the script ScrolluX.JS and to call it !
