About Web Feeds
Web feeds are files that tell what is new on a site.
They are not meant to be viewed directly in a Web browser. Rather, they are read by programs and sites and the headlines from the file are fed into the program.
After installing a Feed Reader, you will be able to add new feeds.
When you see an image like 
, right click on the image, and copy link as or copy shortcut. That will copy the URL of the feed into your clipboard, which when adding a feed, you'll be able to paste in.
Web feeds make it possible for you to learn what is new on a number of sites without having to visit the various homepages and wade through disparate navigation.
