Create a 'div' for your menu and give it a class name.

Inside this you put your 'a' tags and give each one an #id. This is your menu wrapper and it should be set to position:absolute

Next, add a class to each of the sections of your one page site. The class names must match the #ids of the 'a' links you created above. So if your first link has an id of #section1 you then add the class .section1 to your first div. Repeat this for each link you have.

Add jQuery to the head section of your page

Add the jquery.smint.js to the head section of your page

Call the function with the following script:

$(document).ready( function() {
$('.subMenu').smint();
});

You can replace .subMenu with the class name of your menu

To give you a littl emore flexability, the class.fxd gets added to your menu when it becomes fixed to the top of the screen, allowing some extra styleing to be added if needed.
