How do I add an RSS subscription button to my website?

If you'd like to add an RSS subscription button to your blog/website, in your FeedPress dashboard, go to Extras > Subscription Counter (pictured below).

Make sure to grab the code for the style of button you want.

Most modern Content Management Solutions such as WordPress, Tumblr, Blogger, Squarespace, or Wix, provide an easy way to add javascript to a webpage (it's usually a code widget).
