Include the JavaScript SDK on your page once, ideally right after the opening <body> tag.
<div id="fb-root">
<script>(function(d, s, id) {
var js, fjs = d.getElementsByTagName(s)[0];
if (d.getElementById(id)) return;
js = d.createElement(s); js.id = id;
js.src = "//connect.facebook.net/it_IT/all.js#xfbml=1";
fjs.parentNode.insertBefore(js, fjs);
}(document, 'script', 'facebook-jssdk'));</script>
Add an XML namespace to the <html> tag of your document. This is necessary for XFBML to work in earlier versions of Internet Explorer.
<html xmlns:fb="http://ogp.me/ns/fb#">
Place the code for your plugin wherever you want the plugin to appear on your page.
