 In this article, you learn how to utilize [Pulumi](https://pulumi.com) for deployments in Azure Deployment Environments (ADE). You learn how to use a standard image provided by Pulumi or how to configure a custom image to provision infrastructure using the Pulumi Infrastructure-as-Code (IaC) framework.
 
-ADE supports an extensibility model that enables you to create custom images that you can use in your environment definitions. To use this extensibility model, you can create your own custom images, and store them in a container registry like Azure Container Registry (ACR) or DockerHub. You can then reference these images in your environment definitions to deploy your environments.

 An [environment definition](configure-environment-definition.md) comprises at least two files: a Pulumi project file, *Pulumi.yaml*, and a manifest file named *environment.yaml*. It may also contain a user program written in your preferred programming language: C#, TypeScript, Python, etc. ADE uses containers to deploy environment definitions.
