A RSS feed (sometimes known as a web feed) is something you can subscribe to in a piece of software called a RSS reader. The RSS feed contains the titles and summaries of all the latest articles on a given website.
The reader software will periodically check the feed and will show you new articles when they appear without you having to manually check the website. If you think an article is interesting you can click on it in your RSS reader and it will open up the appropriate web page.
Paste the following link into your RRS reader software:
