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.
