Installing the Friendica/Facebook connector
Detailed instructions how to use this plugin can be found at
the [How to: Friendica's Facebook Connector](https://github.com/friendica/friendica/wiki/How-to:-Friendica%E2%80%99s-Facebook-connector) page.
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.
Info: please make sure that you understand all aspects due to Friendica's
default licence which is: [MIT License](https://github.com/friendica/friendica/blob/master/LICENSE)
