Add a Link to another Website in the footer

How do I add a Link to a different website in the footer area?

You mean to replace the credits? Go to Customize > Footer credits and add <a href="http://google.com">External site</a> and adjust as needed.

I have no FOOTER option in the Customizer. Perhaps I have lost my mind, looking over the obvious 100 times, but I simply don’t see it.

I have little experience changing footers in the Editor on other themes, but the child theme throws me. Which theme is the child theme? Yikes!

The footer option is only available in the paid version of the theme.
