Once we have created our extension, including the folders and the files necessary to make it work, we should activate it. Obviously, our extension is currently empty and so it does not add anything to the standard eZ Publish design.

There are two ways to enable an extension. The first is to manually edit the configuration files of eZ Publish, and the second is to access the backend and enable it through a visual interface.
