+# Azure Key Vault Extension
+
+The extension provides a `Vault` implementation interfacing with an Azure Key Vault.
+
+## Authentication
+
+This extension connects to Azure Key Vault using the
+standard `AzureDefaultCredential`
+provided by the Azure Identity library. This generic credential fits most use-cases and will attempt to authenticate via
+a predefined chain of methods until one is successful. More details about the authentication methods used can be found
+in  
+this [page]([DefaultAzureCredential](https://learn.microsoft.com/en-gb/java/api/com.azure.identity.defaultazurecredential?view=azure-java-stable)).
+
+### Example 1: connect with Principal client id and a client secret (see [EnvironmentCredential](https://learn.microsoft.com/en-gb/java/api/com.azure.identity.environmentcredential?view=azure-java-stable))
+
+The following environments variables must be set:
+
+- `AZURE_CLIENT_ID`
+- `AZURE_CLIENT_SECRET`
+- `AZURE_TENANT_ID`
+-
+
+### Example 2: connect with Principal client id and a client certificate (see [EnvironmentCredential](https://learn.microsoft.com/en-gb/java/api/com.azure.identity.environmentcredential?view=azure-java-stable))
+
+The following environments variables must be set:
+
+- `AZURE_CLIENT_ID`
+- `AZURE_CLIENT_CERTIFICATE_PATH`
+- `AZURE_CLIENT_CERTIFICATE_PASSWORD`
+- `AZURE_TENANT_ID`
