An Accelerator is a type of Site template that does much of the work of setting up a store. An Accelerator is a convenient sandbox for gaining familiarity with Liferay Commerce, but it can also be a head start on setting up a live Site.
Typically, an Accelerator gives you a theme, a set of customer-facing pages with a working interface, and a sample catalog.
Accelerating a Site
To set up a Site using an Accelerator, follow these steps:
Go to Control Panel → Sites → Sites.
Click the button and select an Accelerator such as Beryl (subscribers only) or Breccia.
Enter a name for your store and click Submit.
