What is RSS?
RSS (Really Simple Syndication) is a family of web feed formats used to publish frequently updated digital content, such as blogs, news feeds, or podcasts.
Users of RSS content use programs called feed "readers" or "aggregators": the user "subscribes" to a feed by supplying to their reader a link to the feed; the reader can then check the user's subscribed feeds to see if any of those feeds have new content since the last time it checked, and if so, retrieve that content and present it to the user.

In your news reader, select the option that adds a new feed or channel, then paste in the URL and click OK. Click to instantly add content to your page.
If your browser supports it, you can simply click on the RSS icon
