+// Auto-posting requires Facebook's PHP API. It can be found on GitHub.
+// https://github.com/facebook/facebook-php-sdk 
+
+require_once(dirname(__FILE__) . '/facebook-php-sdk/src/facebook.php');
+
+// Obtaining proper credentials will take a few steps, listed below.
+// More here: http://jeremygibbs.com/2012/02/11/how-to-autopost-facebook
+//
+// 1.) Create Facebook App
+//     Go to Facebook app page: https://developers.facebook.com/apps
+//     and click "Create New App" button in top right corner. Choose a 
+//     name (you can leave namespace empty) and continue. Next, you will 
+//     customize the app. Write down App ID and App Secret located in header.
+//     In basic info section, enter email/domain from which you will be 
+//     posting. Finally, declare how the app integrates with Facebook. You 
+//     will likely want the website option. Enter your site's URL and save.
+//
+// 2.) Obtain Credentials
+//     You now must authorize your app to post content on your behalf. 
+//     Normally, once an app is authorized, the user must be logged in to 
+//     verify permissions. You can avoid this by requesting a long-term 
+//     token. To do this, you will create a simple php webpage - grab the 
+//     example here: https://gist.github.com/2114528. Visit the webpage in 
+//     your app, which will forward you to Facebook. You will grant 
+//     permissions and be redirected back to the webpage. That page will 
+//     will display your offline access token. Save this token, and put
+//     it with your App ID and App Secret. Now you are good to go.
