mattelliott on "RSS Feed Missing?"

I'm new to deal with RSS so bear with me if this is basic stuff.
So, from what I have gathered WordPress runs its own feed service and I shouldn't have to set anything up.

However, when I go to the feed url ( http://shephardsummers.com/feed/ ) in the browser I get this :

<rss xmlns:content="http://purl.org/rss/1.0/modules/content/" xmlns:wfw="http://wellformedweb.org/CommentAPI/" xmlns:dc="http://purl.org/dc/elements/1.1/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:sy="http://purl.org/rss/1.0/modules/syndication/" xmlns:slash="http://purl.org/rss/1.0/modules/slash/" version="2.0">

</rss>

It seems to me like I should see some more info here and should see site content not marked up.

I've been tasked with adding an rss subscribe button to this site but I guess I need to sort out the RSS first…?

Any help/advice is greatly appreciated.
Thanks everyone!
