The Quickstart template comes with the JoomlaXTC copyright and legals published in the footer and module positions.
To remove these simply unpublish or edit the modules in the footer and legal module positions.
Each JoomlaXTC template comes with custom themes and extensions for the template. After you do your main install of the template you can install the custom extensions - please view the component or module documentation for docs on installing and configuring these extensions.
The source graphic files that come with the template are not for Joomla installation and are the source PSD designs for the template. You will need a copy of Photoshop to open these layered PSD files.
JoomlaXTC also includes special themes for 3rd party components - For information on installing these themes please view the theme docs - View Theme Docs -
