+## Azure AD Authentication - Information
+To get v2.0 AAD token you need to modify the `Manifest` of your AAD app registration by following the instructions here https://docs.azure.cn/en-us/entra/identity-platform/scenario-protected-web-api-app-registration#accepted-token-version
+
+You can then get the token using this CURL command
+
+```bash
+# replace AadClientId, AadApplicationURI, AadClientSecret, AadTenantId with the AAD details from the azure portal.
+
+curl -X POST -H "Content-Type: application/x-www-form-urlencoded" -d 'client_id={AadClientId}&scope={AadApplication Uri}/.default&client_secret={AadClientSecret}&grant_type=client_credentials' 'https://login.microsoftonline.com/{AadTenantId}/oauth2/v2.0/token'
+```
+
+Once obtaining the token, start the WireMock.Net server, e.g. the `WireMock.Net.StandAlone` package.
+
+```c#
+using WireMock.Logging;
+using WireMock.Net.StandAlone;
+using WireMock.Settings;
+
+var settings = new WireMockServerSettings
+{
+    AllowPartialMapping=true,
+    Logger = new WireMockConsoleLogger(),
+    UseSSL = true,
+    AdminAzureADTenant = "AadTennatId",
+    AdminAzureADAudience = "AadAudience",
+    StartAdminInterface=true
+};
+
+StandAloneApp.Start(settings);
+
+Console.WriteLine("Press any key to stop the server");
+Console.ReadKey();
+```
+
+Make a `GET` request to `{WiremockServerURL}/__admin/requests` with the `Bearer AadToken` set in the `Authorization` header and 200 for success 401 for authentication errors.

 ### FluentBuilder
 All Admin API Model classes are annotated with [FluentBuilder](https://github.com/StefH/FluentBuilder) which makes it easy to build a mapping in a fluent way.
