What are RSS feeds?
RSS feeds allow you to keep up-to-date on your favorite websites by "subscribing" to their feeds. New information added to those sites can be easily browsed by visiting a single web page, called a "news reader". The news reader automatically checks for updates and displays them for you!
Most news readers allow you to subscribe by copying the link from your browser and pasting it into the news reader. Some news readers automatically detect the feed when you click on the link, making subscribing even easier! If in doubt, read your news reader's help guide on how to subscribe to news feeds.
