The TYPO3 Facebook extension is a simple tool to add TYPO3 content in you Facebook Application.
Facebook applications are small programs developed specifically for Facebook profiles. The content of those programs is provided by an external source which could be any website server.
This content may be of a simple html page, a more complex one generated by a CMS or a simple Flash file.
Facebook also provides an API for software developers to create applications that interact with core Facebook features. A markup language called Facebook Markup Language is also available; it is used to customize the "look and feel" of applications that developers create.
This extension helps you to easily create content for your Facebook application directly from TYPO3. It will also allow you to easily add user interface elements of Facebook, so users of your applications can easily share the content of your site through Facebook.
