Disable Feeds WP is a WordPress plugin to disable all RSS/Atom/RDF WordPress feeds on your website/blog. It is very useful if you use WordPress purely as a content management system (and not for blogging). All requests for feeds will be redirected to the corresponding HTML content.
There are a couple of options to tweak the plugin’s behavior – go to <code>Settings -> Reading</code> to see them.
Here’s a link to the documentation for the plugin. This will help you learn more about its features and how to use it.
