A feed is a document that contains summaries of web content with web links to the original versions. It may be viewed with a feed reader or news aggregator. If you simply click on the link without a feed reader, you will see a page of XML code.

To view feeds you need a reader or aggregator that displays the formatted feed. A substantial number of readers are available for all operating systems; many are free. Some are available as standalone programs that you download and install on your computer; others are part of a web browser.

Once you have a reader, you may subscribe to any feed of interest.
