*
- * Register your Friendika site as "Client" application with "Read & Write" access
+ * Register your Friendica site as "Client" application with "Read & Write" access
* we do not need "Twitter as login". When you've registered the app you get the
* OAuth Consumer key and secret pair for your application/site.
*
- * Add this key pair to your global .htconfig.php
+ * Add this key pair to your global .htconfig.php or use the admin panel.

* $a->config['twitter']['consumerkey'] = 'your consumer_key here';
* $a->config['twitter']['consumersecret'] = 'your consumer_secret here';
