I've created an RSS feed, and if you're reading this, my guess is
you want to hear the RSS basics.
An RSS feed is a website's news, and you can subscribe to it with
an RSS reader. Not all websites have an RSS feed, but those that
do have a file called rss.xml or something
like that. Just copy/paste the file's URL to where the RSS reader
wants it and you can have the RSS reader tell you what's new with
whatever the RSS feeds focus on; usually content on the website.
If you don't have an RSS reader, the one I've been using is
newsboat. Just put the URLs to the RSS feeds
into ~/.newsboat/urls, one per line, and run
the newsboat command in your terminal
emulator of choice. If you don't like terminal emulators, I'd
imagine you could find an RSS reader that doesn't make you use one
somewhere online.
