# commercetools Installation

## Before you start

Installing the commercetools integration first in a development
commercetools environment which is an exact copy of the live store is recommended. After verifying
everything is working properly in the development environment, safely install the integration in the live environment.

### Integration Marketplace

The [commercetools integration](https://marketplace.commercetools.com/integration/gr4vy) is available for free
in the commercetools Integration Marketplace.

### Install the integration

The installation and setup of the commercetools integration requires several different modules.

* Merchant Center Custom app
* Extension Module
* Notification Module
* Setup Module

You also need to integrate Embed with your storefront app. Example
code for how to integrate Embed with the default commercetools storefront is provided.

Documentation for installing and configuring each of the modules listed in the preceding section is included
in the [GitHub repository](https://github.com/gr4vy/gr4vy-commercetools) for the integration.
