Paste the code to your ExpressionEngine website’s HTML field.
Next, go to your ExpressionEngine website editor and find the HTML field. It is most likely in the form of an HTML/Code widget or module which you can find on the ExpressionEngine’s editor. Add it to your page, and paste the Social Media & RSS Feeds Embed Code you’ve copied before to the HTML field.
Save and update, and that’s it, you should have Common Ninja’s Social Media & RSS Feeds add-on on your ExpressionEngine website.
