What is it for?
This is a small module, that provides a new commerce checkout pane, the content of which can be configured via rules. This comes useful for example when you want to display a certain message to the user depending on the payment method. Using the "Set an entity to be displayed as completion message" action you can even display a node, order or commerce_invoice as completion message.
Instalation
Enable the module like any other Drupal module:
http://drupal.org/documentation/install/modules-themes/modules-7
After enabling this module, two new rules actions are available that allow you to set a custom message which is displayed by default in the /complete checkout step.
The checkout pane, that displays the message, should be enabled by default. If it is not, you can enable it at admin/commerce/config/checkout/form.
Usage
The module provides a new rules event ("Determine rules checkout pane content") and a two new actions ("Set the completion message" and "Set an entity to be displayed as completion message").
