RSS is an easy way to review updates from your favorite Web sites without visiting each one. With an RSS reader, you subscribe to a feed and scan the headlines. When you find something that interests you, click on the link to read the complete article.
First, get an RSS reader. Then follow your RSS reader's instructions for adding a feed to your list. There are many RSS readers available, some of which are free. There are Web-based readers as well as those that you download and install on your computer. A quick web search will turn up lots of options.
Most modern web browsers also have RSS capabilities built in, though they may call it something a little different.
