Feeds deliver updates to web-based content, and allow you to find out what's new on a website without you having to visit it.
To view a feed, you need either a web-based or desktop reader (also referred to as an "aggregator").
Web-based readers allow you to subscribe to feeds online and view
them in a web browser; desktop readers are software programs or
plug-ins that are installed on your computer. Some examples include:
To subscribe to a feed, right-click (Windows) or ctrl-click (Mac) on the feed
link, and copy the link address. Then go to your feed reader, create a
new subscription or feed, and paste the address when asked.
