-/**
- * Installing the Friendica/Facebook connector
- *
- * Detailed instructions how to use this plugin can be found at
- * https://github.com/friendica/friendica/wiki/How-to:-Friendica%E2%80%99s-Facebook-connector
- *
- * 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.
