+# Azure Virtual Desktop Solution
+
+[**Home**](./README.md) | [**Features**](./docs/features.md) | [**Design**](./docs/design.md) | [**Prerequisites**](./docs/prerequisites.md) | [**Troubleshooting**](./docs/troubleshooting.md)
+
+This Azure Virtual Desktop (AVD) solution will deploy a fully operational [stamp](https://learn.microsoft.com/azure/architecture/patterns/deployment-stamp) in an Azure subscription adhereing to the [Zero Trust principles](https://learn.microsoft.com/security/zero-trust/azure-infrastructure-avd). Many of the [common features](./docs/features.md) used with AVD have been automated in this solution for your convenience. Be sure to complete the necessary [prerequisites](./docs/prerequisites.md) and to review the parameter descriptions to the understand the consequences of your selections.
+
+## Deployment Options
+
+> [!WARNING]
+> Failure to complete the [prerequisites](./docs/prerequisites.md) will result in an unsuccessful deployment.
