Just include the Javascript file after you've included jQuery.
You need at least jQuery 1.4.2, but use the latest jQuery to get better performance
first make the global menu just as no style. just make sure that you get the .main and .menu in html.
<div id="circle">
<a class="main"><img src="img/main.png" ></a>
<a class="menu" href=""><img src="img/home.png" ></a>
<a class="menu" href=""><img src="img/profile.png" ></a>
<a class="menu" href=""><img src="img/schedule.png" ></a>
<a class="menu" href=""><img src="img/group.png" ></a>
<a class="menu" href=""><img src="img/add.png" ></a>
<a class="menu" href=""><img src="img/search.png" ></a>
<a class="menu" href=""><img src="img/config.png" ></a>
<a class="menu" href=""><img src="img/add.png" ></a>
</div>
$("#circle").circle(option);
the option is unnecessary,but you can customize it to make new action,also.
