When a reader enjoys one of your posts, they want to share it! Make it easy for them to do so by adding Facebook, Twitter, and Pinterest sharing buttons to the footer of your posts and pages.
Go to Design > Content for your blog and click the pencil icon next to the Post Footer module. Check the boxes next to the social accounts you wish to add. Click OK and Save Changes. That's it! You do the same for Pages by editing the Page Footer module.
Check out the footer at the end of this post to see how the buttons will look!
