How to Edit the Site Footer Text

Head to Appearance > Customize > Theme Settings > Footer

Anything you place here will override the entire footer text. You can add html links and shortcodes here. So if you'd like to add an extra link, it might look like this:
Copyright [footer_copyright first="2020"] &middot; <a href="https://yourwebsite.com/" target="_blank">LINK TITLE</a> &middot; YOUR BLOG NAME HERE &middot; <a href="https://heartenmade.com" target="_blank">Hearten Made</a>
		
Replace the URL with the link to the page you want, and replace LINK TITLE with the title of the link. Replace YOUR BLOG NAME HERE with your own site title.
