 ## Step 1: Configure Entra ID
 
-Before your applications can interact with Entra ID, they must be registered with a tenant that you manage. This can be either an Entra ID (Azure AD) tenant, or an Entra ID B2C (Azure AD B2C) tenant. For more information on creating an Azure AD B2C tenant, see [Microsoft's Tutorial: Create an Azure Active Directory B2C tenant](https://learn.microsoft.com/en-us/azure/active-directory-b2c/tutorial-create-tenant).
+Before your applications can interact with Entra ID, they must be registered with a tenant that you manage. This can be either an Entra ID (Azure AD) tenant or an Entra ID B2C (Azure AD B2C) tenant. For more information on creating an Azure AD B2C tenant, see [Microsoft's Tutorial: Quickstart: Use your Azure subscription to create an external tenant](https://learn.microsoft.com/en-us/entra/external-id/customers/quickstart-tenant-setup).
+
+Follow these steps to register your web application with your Entra tenant and configure it for member sign-in:
+
+1. Follow the instructions in [Register an application in Microsoft Entra ID](https://learn.microsoft.com/en-us/entra/identity-platform/quickstart-register-app?tabs=client-secret) using the [Microsoft Entra admin center](https://entra.microsoft.com/).
+
+2. On the **App Registrations** screen, copy the **Application (Client) ID** value. You will need this in your code later. 
+3. Click **Add a certificate or secret**.
+
+![Entra Example: App Registration Screen](<../../../13/umbraco-cms/tutorials/images/Entra-Example-App-Registration-ClientCredentials.png>)
+
+4. Add a new client secret and copy the generated **Value**. You will use this in your code as well.
+
+
+5. Return to the **Overview** screen and click **Add a Redirect URI**.
+
+6. Add full URLs for all of your applicable environments (local, dev, live, etc.) with the path `/umbraco-b2c-members-signin` appended. For example, `https://mysite.com/umbraco-b2c-members-signin`.
