  <div id="fb-root"></div>
  <script>
    window.fbAsyncInit = function() {
      FB.init({
        appId      : 'This is where My App ID was...', // App ID
        channelUrl : '//www.Icannnotshowyou.com/', // Channel File
        status     : true, // check login status
        cookie     : true, // enable cookies to allow the server to access the session
        xfbml      : true  // parse XFBML
      });

      //put something here?

    });

    };
    // Load the SDK Asynchronously
    (function(d){
       var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
       if (d.getElementById(id)) {return;}
       js = d.createElement('script'); js.id = id; js.async = true;
       js.src = "//connect.facebook.net/en_US/all.js";
       ref.parentNode.insertBefore(js, ref);
     }(document));
  </script>
<div class="fb-login-button">Login with Facebook</div>
