- * 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
