Jenks FAQ and Tips and Tricks
Child themes for the Jenks theme
In order to preserve your original theme, you should use Child Themes to apply modifications to your Jenks theme, without having to modify any of the original theme files.
Download the default child themes for Jenks below. Unzip and upload the child Theme to your themes folder (make sure that Jenks as a parent theme is installed - but not activated as well), and activate it, just as you would activate any other theme. There is a README.TXT included in the child theme with further information.
As an addon feature, the child themes enable the WordPress 3 navigation system, and the use of featured posts images, or post thumbnails, as described in this article. Featured images can be added using the featured images option on the write post panel.
