Add clusterer to google maps v2 api

I've been trying for quite awhile to add a clusterer to my google map but I've had no luck. I understand that I have to import the library for the c开发者_如何学Golusterer to my html but beyond that I am unsure. If anyone could point me in the right direction that would be great (I am looking for something more in-depth than a link to the documentation for the clusterer, I've already reviewed that enough :/). This page has the code for the map that I am speaking of: www.thebboymap.info.

This is a great example for what you are looking for.
