First, create a folder called “mvigilance.”
In that folder, create a screenshot.png and a style.css.
Here is a sample of what you paste into your style.css.
(beginning of file)
/*
Theme Name: myvigilance
Theme URI: http://wordpress.org/
Description: This is a child theme of Vigilance
Version: 1
Author: Ray Choi
Author URI: http://www.raychoi.org
Template: vigilance
*/
/* Template: vigilance */
@import url(../vigilance/style.css);
/* Header */
(end of file)
You’ll notice that this child theme is inheriting from the Vigilance parent theme.
Lastly, upload/ftp this child theme “myvigilance” folder to your themes directory.
