There's a few ways you can integrate the 2.
* On your website, you can use the JFBCFan module to show the users that have Like'd your page and your recent activity stream.
* On your Facebook Page, you can create a "Page Tab" icon in the bottom right of your Cover Photo area which will show your website when clicked. You can configure that in the Page Tab / Canvas settings in the JFBConnect administrator area.
Hope that helps, but if there's something specific you're looking for, let us know.
Thanks,
Alex
