Rest assured, I’m very much a normie with tech stuff too. It wasn’t bad to set up. It’s been a few months, but I’m sure I just downloaded it from the link on their site and followed the installation prompts.

The hardest part is finding websites that support RSS. But for an example, say you wanted to receive reports about outbreaks from the FDA, here’s their RSS feed: https://www.fda.gov/about-fda/contact-fda/stay-informed/rss-feeds/fda-outbreaks/rss.xml

You would just go to “add feed” in the RSS reader, and paste the URL, and you’re done! You can customize how often you want it to check your feeds for new updates (I have mine check every couple of hours), and when they show up, you can view them within your reader similar to email.
