How to add a RSS feed to my WordPress site

Hi William, The RSS Widget is the easiest way to display posts from any RSS feed. You might find this handy if you want to show off one of your other blogs, or one of your favorite blogs, in your sidebar. You can find this handy widget in Appearance > Widgets, or via the Customizer. Once you add the RSS widget to your sidebar or footer, you’ll be prompted to enter the URL of the RSS feed from the blog or web site you would like to display. Configure the remaining options in the widget, and you'll be set!
