Kentico CMS allows you to publish content using a RSS 2.0 feed.The default installation contains a simple CMSPages\NewsRss.aspx page that shows how to build your own RSS feed. It works with news items, but you can modify the code so that it displays a different type of documents.
For more details and information about RSS Feeds and about how to create RSS Feed for a different type of documents please refer to the Module RSS Feeds chapter in Kentico CMS Developer's guide.
