RSS feed
RSS feed is a resource that allows you to receive updates (including entire texts) from a website without having to visit it. To do this, simply install a RSS feed reader on your computer or cell phone (such as Newsblur (which works in the browser) or Feeder (for Android phones, via F-Droid).
It's simple: place your mouse over the “RSS” or “RSS feed” link or the RSS icon (which you can find on many websites), click the right mouse button, copy the link and register it with Newsblur, Feeder or another RSS reader you use.
