RSS and Atom are the two feed formats that help to keep you updated on latest content from your favourite websites using an XML format. Instead of having to revisit a website to see if it has fresh content, you can view an aggregation of latest headlines via a feed reader which collects news from your selected websites. Right now, IDA supports RSS 2.0 and Atom 1.0 which are supported by most feed readers.
You will need to download a program called an aggregator. This provides a user-friendly interface to read the RSS / Atom information feeds from your favourite websites on your computer. You can also subscribe to new RSS / Atom feeds or manage your existing feeds via the reader.
There is a range of feed readers available online. Different readers work on different operating systems, so please take this into account when you choose one, and follow the instructions.
