Getting the Facebook Connect API Key
To begin using Facebook Connect you must obtain API Key and Application Secret from Facebook. To do so you should first sign in to Facebook at http://facebook.com
After signing in you need to go to http://facebook.com/developers/. The page you'll see is shown below.

The page where you can allow access to "Developer" application
You should click "Allow". When you are done, you'll be taken to the page featuring different information about this application.

"Set Up New Application" button on the "Developer" page
In the upper right corner you'll find "Set Up New Application" button. You should click it. It will take you to the first step of the process of registering your application (which is your website).

First form you need to fill to register your application
Enter your website title in the "Application Name" field and set "Terms" radio-button to "Agree". Now click "Save Changes" button. It will take you to a big form that you can fill in. All those fields are optional so we leave them blank as for now. At the top of that form you can see API Key and Application Secret. You will need to enter this in your Joomla configuration.

The last information that Facebook needs to get is Connect URL. Please click "Connect" button in the left vertical menu. The top field of the page is the Connect URL field and you need to enter your site URL there.
