 - Specific headers
 - Cookies

-You can manually apply these configured headers, cookies, and credentials on the page you are recording from and then record steps your test performs post-login.

 ## Account security
 
 ### Secure your authentication data
 
 Store your credentials as [global variables][7] (for example, one global variable for username, another one for password) and select **Hide and obfuscate variable value** to hide their values from test results. You can restrict permissions on a browser test for individuals who have access to your instance of Datadog.
 
-Once you create the obfuscated variables, you can then [import these global variables][8] into your browser tests and leverage them for your login steps.
+After you create the obfuscated variables, you can then [import these global variables][8] into your browser tests and use them in your login steps.
 
 **Note:** Although Datadog global variables are securely stored and encrypted, it is strongly recommended that you use an account dedicated to testing with dummy credentials as a general testing best practice.

+## Overview
+
+Datadog Synthetic Monitoring enables proactive monitoring of web applications and APIs using Kerberos SSO authentication with Microsoft Active Directory. This allows continuous testing of critical user journeys and HTTP endpoints on your internal Windows sites.
+
+## Prerequisites
+
+- A Windows site with Kerberos authentication integrated with Active Directory (usually hosted on IIS).
+- A Windows server that is domain-joined to the Active Directory.
+- A domain user account with Active Directory authentication access to the Windows site.
+- Synthetic Monitoring tests must run on a Windows private location that is configured to authenticate with Active Directory. For more information, see the [Windows private locations][1] prerequisites documentation.
+
+## Installation
+
+1. Create your [Windows private location][2] on the Windows server joined to the Active Directory domain.
+2. Set up the [Synthetic Monitoring private location worker][3] to run as a Windows service.
+3. Configure the private location service to use your Active Directory domain account credentials:
+   - Open `services.msc`, navigate to **Datadog Synthetics Worker** > **Properties** > **log on** > **this account**, and enter your domain account credentials.
+4. Configure your tests to run from the Windows private location (managed locations do not support Kerberos authentication).
+
+<p style="text-align: center;"><em>No further configuration is necessary for Browser Tests.</em></p>
+
+5. Optionally, for API tests, you must also set the Domain field to your Active Directory domain name under the **Kerberos** tab. Navigate to **Create/Edit API Test** > **Define Request** > **Advanced Options** > **Authentication**.
