For a really simple way to add the Facebook feed, you can use the Facebook Page Plugin. An example of that can be found below:
developers.facebook.com/docs/plugins/page-plugin/
That's limited in how it looks and can be styled, and only works for Facebook. If that's what you're looking for though, you can setup and configure that plugin using the SCSocialWidget module.. just configure a Facebook -> Page Plugin type of widget and set the parameters for your Facebook Page to display.
If you want to have a customized stream that can show data from Twitter, Facebook and/or LinkedIn, you'll need to let the owners of those feeds authenticate on your site, even if that's you. Once you have the user's authenticated and the Stream setup, you can hide the SCLogin module and make it so no one else can authenticate. However, we need the owners to authenticate to give permission to read the feeds from their account.
For setting up the streams, the general process is:
* Setup apps for the social network(s) you want to show a stream for - This allows for authentication
* Login with the user that owns the feed on those social networks
* Setup a channel, selecting the user that already authenticated
* Have that user re-authenticate on the front-end to grant any additional permissions that may be required for the stream
* Configure the SCSocialStream module to display the feed(s) how you want
It can be tedious, we understand, but we've tried to simplify it as much as we can.. Once it's setup, you shouldn't need to go through the process again and you'll have the full ability to style the streams with HTML and CSS, which can be very powerful.
I hope that helps, but if you're running into specific issues, let us know what they are, and we'll gladly help!
