I decided to download the Genesis Metro Child theme. Took a copy of the full folder.
I renamed the copied folder to Custom and the Theme Name information seen inside the top area of the style.css file to Custom. Then adjusted other information as well.
The style.css file.
/*
Theme Name: Custom
Theme URI: https://www.easywebdesigntutorials.com
Description: A custom Genesis child theme
Author: Paal Joachim Romdahl
Author URI: https://www.easywebdesigntutorials.com
Version: 1.0
Template: genesis
Template Version: 2.0.0
*/
/* Import CSS files */
@import url(assets/css/forms.css);
@import url(assets/css/widgets.css);
@import url(assets/css/nav.css);
@import url(assets/css/theme-colors.css);
@import url(assets/css/custom.css);
The functions.php file I changed.
//* Child theme (do not remove)
define( 'CHILD_THEME_NAME', __( 'Custom Theme', 'custom' ) );
define( 'CHILD_THEME_URL', 'https://www.easywebdesigntutorials.com/easywebdesigntutorials.com/' );
define( 'CHILD_THEME_VERSION', '1.0' );
