 ## Resources shared with Microsoft Dev Box
 
 Azure Deployment Environments and Microsoft Dev Box are complementary services that share certain architectural components. Dev centers and projects are common to both services, and they help organize resources in an enterprise. You can configure projects for Deployment Environments and projects for Dev Box resources in the same dev center.

 # What is Azure Deployment Environments?
 
 Azure Deployment Environments empowers development teams to quickly and easily spin up app infrastructure with project-based templates that establish consistency and best practices while maximizing security. This on-demand access to secure environments accelerates the stages of the software development lifecycle in a compliant and cost-efficient way.
 
-A deployment environment is a preconfigured collection of Azure resources deployed in predefined subscriptions. Azure governance is applied to those subscriptions based on the type of environment, such as sandbox, testing, staging, or production.
+A [*deployment environment*](./concept-environments-key-concepts.md#environments) is a collection of Azure infrastructure resources defined in a template called an [*environment definition*](./concept-environments-key-concepts.md#environment-definitions). Developers can deploy infrastructure defined in these templates in subscriptions where they have access, and build their applications on the infrastructure. For example, you can define a deployment environment that includes a web app, a database, and a storage account. Your web developer can begin coding the web app without worrying about the underlying infrastructure.

+Platform engineers can create and manage the environment definitions. To specify which environment definitions are available to developers platform engineers can associate environment definitions with projects, and assign permissions to developers. They can also apply Azure governance to the subscriptions based on the type of environment, such as sandbox, testing, staging, or production.
 
-With Azure Deployment Environments, your platform engineer can enforce enterprise security policies and provide a curated set of predefined infrastructure as code (IaC) templates. 
+The following diagram shows an overview of Azure Deployment Environments capabilities. Platform engineers define infrastructure templates and configure subscriptions, identity, and permissions. Developers create environments based on these templates, and build and deploy applications on the infrastructure. Environments can support different scenarios, like on-demand environments, sandbox environments for testing, and CI/CD pipelines for continuous integration and continuous deployment.
 
->[!NOTE]
-> Azure Deployment Environments currently supports only Azure Resource Manager (ARM) templates.

 ## Usage scenarios
 
-Azure Deployment Environments enables usage [scenarios](./concept-environments-scenarios.md) for both DevOps teams and developers. Common scenarios include:
-
-- Quickly create on-demand Azure environments by using reusable IaC templates.
-- Create [sandbox environments](concept-environments-scenarios.md#sandbox-environments-for-investigations) to test your code.
-- Preconfigure various types of environments and seamlessly integrate with your continuous integration and continuous delivery (CI/CD) pipeline.
-- Create preconfigured environments for trainings and demos.
-
-### Developer scenarios
-
-Developers have the following self-service experience when working with [environments](./concept-environments-key-concepts.md#environments).
-
-- Deploy a preconfigured environment for any stage of the development cycle.
-- Spin up a sandbox environment to explore Azure.
-- Create platform as a service (PaaS) and infrastructure as a service (IaaS) environments quickly and easily by following a few simple steps.
-- Deploy environments right from where they work.
-
-Developers create and manage environments for Azure Deployment Environments through the [developer portal](./quickstart-create-access-environments.md), with the [Azure CLI](./how-to-create-access-environments.md) or with the [Azure Developer CLI](./how-to-create-environment-with-azure-developer.md).

+Azure Deployment Environments helps platform engineers apply the right set of policies and settings on various types of environments, control the resource configuration that developers can create, and track environments across projects. They perform the following tasks:  
 
 - Provide a project-based, curated set of reusable IaC templates.
 - Define specific Azure deployment configurations per project and per environment type.
 - Provide a self-service experience without giving control over subscriptions.
 - Track costs and ensure compliance with enterprise governance policies.

+Developers can create environments whenever they need them, and develop their applications on the infrastructure. They can use Azure Deployment Environments to do the following tasks:
 
+- Deploy a preconfigured environment for any stage of the development cycle.
+- Spin up a sandbox environment to explore Azure.
