On the confirmation screen, you will also be presented with HTML code that you can use in your website's <head></head>
tag. This easiest way to copy this block of code is to click the Copy HTML to clipboard button in the Favvy plugin.
Once you've copied the HTML, you'll be able to open up a code editor and paste the HTML into your <head></head>
tag. Please sure that the paths to your icons are updated as needed, depending on where they're located in your directory structure and/or on your server.
