   4  * Installing the Friendika/Facebook connector
   5  *
   6  * 1. register an API key for your site from developer.facebook.com
   7  *   a. We'd be very happy if you include "Friendika" in the application name
   8  *      to increase name recognition. The Friendika icons are also present
   9  *      in the images directory and may be uploaded as a Facebook app icon.
  10  *      Use images/friendika-16.jpg for the Icon and images/friendika-128.jpg for the Logo.
  11  *   b. The url should be your site URL with a trailing slash.
  12  *      You may use http://portal.friendika.com/privacy as the privacy policy
  13  *      URL unless your site has different requirements, and
  14  *      http://portal.friendika.com as the Terms of Service URL unless
  15  *      you have different requirements. (Friendika is a software application
  16  *      and does not require Terms of Service, though your installation of it might).
  17  *   c. Set the following values in your .htconfig.php file
  18  *         $a->config['facebook']['appid'] = 'xxxxxxxxxxx';
  19  *         $a->config['facebook']['appsecret'] = 'xxxxxxxxxxxxxxx';
  20  *      Replace with the settings Facebook gives you.
  21  * 2. Enable the facebook plugin by including it in .htconfig.php - e.g.
  22  *     $a->config['system']['addon'] = 'plugin1,plugin2,facebook';
  23  * 3. Visit the Facebook Settings section of the "Settings->Plugin Settings" page.
  24  *    and click 'Install Facebook Connector'.
  25  * 4. This will ask you to login to Facebook and grant permission to the
  26  *    plugin to do its stuff. Allow it to do so.
  27  * 5. You're done. To turn it off visit the Plugin Settings page again and
  28  *    'Remove Facebook posting'.
  29  *
  30  * Vidoes and embeds will not be posted if there is no other content. Links
  31  * and images will be converted to a format suitable for the Facebook API and
  32  * long posts truncated - with a link to view the full post.
  33  *
  34  * Facebook contacts will not be able to view private photos, as they are not able to
  35  * authenticate to your site to establish identity. We will address this
  36  * in a future release.
