/**
- * Installing the Friendika/Facebook connector
+ * Installing the Friendica/Facebook connector
*
* 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
+ * a. We'd be very happy if you include "Friendica" in the application name
+ * to increase name recognition. The Friendica 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.
+ * Use images/friendica-16.jpg for the Icon and images/friendica-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).
+ * Friendica is a software application and does not require a Privacy Policy
+ * or Terms of Service, though your installation of it might. Facebook may require
+ * that you provide a Privacy Policy, which we find ironic.
* c. Set the following values in your .htconfig.php file
* $a->config['facebook']['appid'] = 'xxxxxxxxxxx';
* $a->config['facebook']['appsecret'] = 'xxxxxxxxxxxxxxx';
* d. Navigate to Set Web->Site URL & Domain -> Website Settings. Set
* Site URL to yoursubdomain.yourdomain.com. Set Site Domain to your
* yourdomain.com.
- * 2. Enable the facebook plugin by including it in .htconfig.php - e.g.
- * $a->config['system']['addon'] = 'plugin1,plugin2,facebook';
+ * 2. Visit the Facebook Settings section of the "Settings->Plugin Settings" page.
+ * and click 'Install Facebook Connector'.
* 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
+ * 5. Optional step: If you want to use Facebook Real Time Updates (so new messages
+ * and new contacts are added ~1min after they are postet / added on FB), go to
+ * Settings -> plugins -> facebook and press the "Activate Real-Time Updates"-button.
+ * 6. 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
* authenticate to your site to establish identity. We will address this
* in a future release.
