Installing the module
Installing the module is no different from any other Joomla! package. Go to the My Downloads Page; you’ll find there a file called mod_web7_video.zip, which contains the core Joomla 3-compatible module files. Download this file.
Head over to the Joomla Administration and go to Extensions -> Manage -> Install. Now you can drag&drop mod_web7_facebook.zip and Joomla will do the rest.
Setting up the module
After you install the module, go to Extensions -> Modules and find Web7 Facebook Gallery. After opening an administration of the module, you can see quick setup guide and important links.
Head over to Settings (third tab) and insert your Facebook page name (If you didn't assign a name to your page, you have to do it.)
Now you can choose a position and publish your module.
