RSS (or Really Simple Syndication) feeds are free content feeds from Web sites that contain article headlines, summaries and links back to full-text articles on the web.
To start using RSS, you need a special news reader or aggregator that displays RSS content feeds from Web sites you select. There are many different news readers available, many of which are free of charge. Most are available as desktop software that you download and install on your computer. Several Web-based news readers are available as well.

Once you have set up your news reader, you simply subscribe to the RSS content feeds you want.
RSS is an easy way for you to be alerted when content that interests you appears on your favorite Web sites. Instead of visiting a particular Web site to browse for new articles and features, RSS automatically tells you when something new is posted online.
Click on the orange XML button to obtain the RSS URL, which you will see in the "Address" field of of your browser. Simply copy this URL and follow the instructions for your particular news reader to subscribe.
