RSS

To generate an RSS file from the metadata of your _posts, you need to provide the following data in your _cobalt.yml:

# path where the RSS file should be generated
posts:
  title: My blog!
  description: Blog description
  rss: rss.xml
site:
  base_url: http://example.com

None of these fields are optional, as by the RSS 2.0 spec.

Make sure to also provide the fields title, published_date in the front matter of your posts.
