Hi,

I have found this two documents:

http://support.themely.com/knowledgebase/how-to-create-a-child-theme/

http://support.themely.com/knowledgebase/integral-lite-pro-child-themes/

But not totally clear how to proceed. Do I need to install the zip file as an new Theme and that is it. Or manually edit the functions.php? And what should be the file permissions.

Thanks Rob
