Welcome to the wonderful world of feeder! To get started, you really need to add some feeds. Here’s how:
A feed is a special file provided by websites. This file contains a list of things that might be interesting for its visitors. For a blog it might be blog posts. For a webstore it might be the latest arrivals, or for a social media website it might be the latest posts on the site.
What’s important is how to find them. Usually there is a link on the site with the text “RSS” or “Atom“. A lot of site use icons to denote the existence of feeds.
