How to make a child theme after style.css has been customized

Vote count:

-1

I am working on a theme that has already been customized. Only one file in the theme has been customized, that file is the style.css. A child theme was NOT created before doing the customizations.

I would like to make a child theme so the customizations are not lost when the theme is upgraded. How do I add the customizations in the style.css to new child theme?

Thank you.
