  41  *   License:3-clause BSD license
  42  *
  43  *   Configuration:
  44  *     To use this plugin you need a OAuth Consumer key pair (key & secret)
  45  *     you can get it from Twitter at https://twitter.com/apps
  46  *
  47  *     Register your Friendica site as "Client" application with "Read & Write" access
  48  *     we do not need "Twitter as login". When you've registered the app you get the
  49  *     OAuth Consumer key and secret pair for your application/site.
  50  *
  51  *     Add this key pair to your global .htconfig.php or use the admin panel.
  52  *
  53  *     $a->config['twitter']['consumerkey'] = 'your consumer_key here';
  54  *     $a->config['twitter']['consumersecret'] = 'your consumer_secret here';
  55  *
  56  *     To activate the plugin itself add it to the $a->config['system']['addon']
  57  *     setting. After this, your user can configure their Twitter account settings
  58  *     from "Settings -> Plugin Settings".
