## Prerequisites
<a name="managedintegrations-sdk-codegen-env-prereq"></a>

Install the following items before you configure your environment:
+ Git
+ Python 3.10 or higher
+ Poetry 1.2.0 or higher

## Configure your environment
<a name="managedintegrations-sdk-codegen-env-setup"></a>

Use the following procedure to configure your environment to use the codegen.py code generator.

1.  Download the latest version of the [End device SDK](managedintegrations-sdk-devices.md) from the AWS Management Console. 

1. <a name="managedintegrations-sdk-codegen-python"></a>Set up the Python environment. The **codegen** project is python-based and uses Poetry for dependency management.

   1. Install project dependencies using poetry in the `codegen` directory:

     ```
     poetry run poetry install --no-root
     ```

1. <a name="managedintegrations-sdk-codegen-repo"></a>Set up your repository.

   1. Clone the **connectedhomeip** repository. It uses the `codegen.py` script located in the `connectedhomeip/scripts/` folder for code generation. For more information, see [connectedhomeip](https://github.com/project-chip/connectedhomeip) on *GitHub.*

      ```
      git clone -b v1.4.0.0 https://github.com/project-chip/connectedhomeip.git
      ```

   1. Clone it at the same level as your `IoT-managed-integrations-End-Device-SDK ` root folder. Your folder structure should match the following:

      ```
        |-connectedhomeip
        |-IoT-managed-integrations-End-Device-SDK
      ```

**Note**  
You don't need to recursively clone submodules.
