+
+# Azure Deployment Environments Preview Azure CLI extension
+
+In addition to the Azure admin portal and the developer portal, you can use the Deployment Environments Azure CLI extension to create resources. Azure Deployment Environments and Microsoft Dev Box use the same Azure CLI extension, which is called `devcenter`.
+
+## Install the Deployment Environments CLI extension 
+
+To install the Deployment Environments Azure CLI extension, you first need to install the Azure CLI. The following steps show you how to install the Azure CLI, then the Deployment Environments CLI extension.
+
+1. Download and install the [Azure CLI](/cli/azure/install-azure-cli).
+
+1. Install the Deployment Environments CLI extension
+``` azurecli
+az extension add --name devcenter
+```
+1. Check that the `devcenter` extension is installed 
+``` azurecli
+az extension list
+```
+### Update the Deployment Environments CLI extension
+You can update the Deployment Environments CLI extension if you already have it installed.
+
+To check the version of the extension that's installed
+``` azurecli
+az extension --version
+```
+
+To update a version of the extension that's  installed
+``` azurecli
+az extension update --name devcenter
+```
+### Uninstall the Deployment Environments CLI extension
+
+To uninstall the extension, use the following command
+```azurecli
+az extension remove --name devcenter
+```
+
+## Get started with the Deployment Environments CLI extension
+
+1. Sign in to Azure CLI with your work account.
+
+    ```azurecli
+    az login
+    ```
+
+1. Set your default subscription to the subscription where you're creating your specific Deployment Environments resources.
+
+    ```azurecli
+    az account set --subscription {subscriptionId}
+    ```
+
+1. Set default resource group. Setting a default resource group means you don't need to specify the resource group for each command.
+
+    ```azurecli
+    az configure --defaults group={resourceGroupName}
+    ```
+
+1. Get Help for a command
+
+    ```azurecli
+    az devcenter admin --help
+    ```
+
+## Next steps
+
+For complete command listings, refer to the [Microsoft Deployment Environments and Azure Deployment Environments Azure CLI documentation](https://aka.ms/CLI-reference).
