CAPITALIZED words refer to a folder or language that you choose. We use CUSTOM for your template and ENGLISH for your language by default. These generic terms should be changed to  the name of the  template/language you are using.

If you want to change "Congratulations! You have successfully installed your Zen Cart™; E-Commerce Solution" with your own text open the includes/languages/ENGLISH/index.php file and find the following code:

// This section deals with the "home" page at the top level with no options/products selected
/*Replace this text with the headline you would like for your shop. For example: 'Welcome to My SHOP!'*/
define('HEADING_TITLE', 'Congratulations! You have successfully installed your Zen Cart™ E-Commerce Solution.');
} elseif ($category_depth == 'nested') {
// This section deals with displaying a subcategory
/*Replace this line with the headline you would like for your shop. For example: 'Welcome to My SHOP!'*/
define('HEADING_TITLE', 'Congratulations! You have successfully installed your Zen Cart™ E-Commerce Solution.');
}

Replace the text starting “Congratulations” with your own text. Make sure that the single quote marks are not left out.

Save the edited file to includes/languages/ENGLISH/CUSTOM/index.php and upload it to your server.
