# Getting Started: Installation

To add the Wix eCommerce platform’s functionality to a site, a Wix user needs to install it as an app. However, unlike other Wix apps, the eCommerce platform can't be installed by itself. Instead, the Wix eCommerce app is added automatically as a dependency when installing a business solution app that relies on its functionalities, such as [Wix Bookings](https://support.wix.com/en/article/wix-bookings-about-wix-bookings), [Wix Stores](https://support.wix.com/en/article/wix-stores-about-wix-stores), [Wix Restaurants Orders](https://www.wix.com/app-market/wix-restaurants-orders-new), or a business solution app you develop.

The following articles explain how developers building different types of products should handle installation of the eCommerce app:
