Every website managed by Fargo has an RSS feed.
If the URL of your website is http://mysite.com/, the feed is at http://mysite.com/rss.xml.
All items that are added via the + icon are automatically in the feed.
If you want another item to be in the feed, add an isFeedItem attribute with the value true.
Fargo also supports podcasts. If you have the URL to an MP3 (or any other type) create an enclosure attribute on the main headline of the post. Fargo will fill in the enclosureLength and enclosureType attributes automatically.
Here's a screen shot of the attributes on my test podcast post.
