/**
- * This module needs a lot of work.
+ * Installing the Friendika/Facebook connector
*
- * - setting/storing preferences
- * - documentation on how to obtain FB API keys for your site
- * - ensuring a valid FB login session
- * - requesting permissions within the FB login session to post on your behalf until permission revoked.
+ * 1. register an API key for your site from developer.facebook.com
+ * a. We'd be very happy if you include "Friendika" in the application name
+ * to increase name recognition. The Friendika icons are also present
+ * in the images directory and may be uploaded as a Facebook app icon.
+ * Use images/friendika-16.jpg for the Icon and images/friendika-128.jpg for the Logo.
+ * b. The url should be your site URL with a trailing slash.
+ * You may use http://portal.friendika.com/privacy as the privacy policy
+ * URL unless your site has different requirements, and
+ * http://portal.friendika.com as the Terms of Service URL unless
+ * you have different requirements. (Friendika is a software application
+ * and does not require Terms of Service, though your installation of it might).
+ * c. Set the following values in your .htconfig.php file
+ * $a->config['facebook']['appid'] = 'xxxxxxxxxxx';
+ * $a->config['facebook']['appsecret'] = 'xxxxxxxxxxxxxxx';
+ * Replace with the settings Facebook gives you.
+ * 2. Enable the facebook plugin by including it in .htconfig.php - e.g.
+ * $a->config['system']['addon'] = 'plugin1,plugin2,facebook';
+ * 3. Visit the Facebook Settings section of the "Settings->Plugin Settings" page.
+ * and click 'Install Facebook Connector'.
+ * 4. This will ask you to login to Facebook and grant permission to the
+ * plugin to do its stuff. Allow it to do so.
+ * 5. You're done. To turn it off visit the Plugin Settings page again and
+ * 'Remove Facebook posting'.
*
+ * Vidoes and embeds will not be posted if there is no other content. Links
+ * and images will be converted to a format suitable for the Facebook API and
+ * long posts truncated - with a link to view the full post.
+ *
+ * Facebook contacts will not be able to view private photos, as they are not able to
+ * authenticate to your site to establish identity. We will address this
+ * in a future release.
