Using RSS is simple - all you need is an RSS reader, such as Feedly or Inoreader, where you can subscribe to RSS feeds by copying and pasting the feed URL, and then view all the content in one place.

To use an RSS feed reader, you can follow these steps:

1. Choose an RSS reader such as Feedly, Inoreader, or NewsBlur.
2. Sign up for an account or log in if you already have one.
3. Find the RSS feed you want to subscribe to and copy its URL.
4. In your RSS reader, click "Add Feed" or a similar button, and paste the URL into the designated field.
5. Your RSS reader will start pulling in new content from the feed, and you can read it all in one place.
6. Customize your RSS reader's settings and preferences to suit your needs, such as organizing feeds into folders, marking items as read, and setting up notifications.
