Find official and third party extensions and themes and install them with one click.
The Marketplace is divided into a section for extensions and one for themes. You can navigate between those using the tabs at the top of the interface.
When clicking on the preview of each extension or theme a modal window will open that contains further information on the product. Just hit the Install button in the upper right corner. Make sure to activate the package afterwards in the System section of the Pagekit administration.
