+
+This guide will assist you in effectively integrating CodeRabbit with SaaS Azure DevOps.
+
+## How it works
+
+For the CodeRabbit app to post reviews on merge requests, it needs to interact with the Azure DevOps API, which requires a Personal Access Token. This token can be generated by creating a Personal Access Token from one of your existing users.
+
+You can create a new user in Azure DevOps and generate a Personal Access Token for that user, following [our recommendations](#recommendations).
+
+## Azure DevOps Personal Access Tokens
+
+To interact with the Azure DevOps API, a **Personal Access Token** is required. This token can be generated by creating a **Personal Access Token** from one of your existing users.
+
+Upon first login to the application (immediately after the onboarding screen), you will need to add the Personal Access Token.

+
+#### Recommendations
+
+* **Create a dedicated user for CodeRabbit** - This ensures the user is exclusively for CodeRabbit, allowing better access control.
+* **Use "CodeRabbit" as the username** - This makes the user easily recognizable for future reference.
+* **Use a dedicated email address** - This helps in easy identification and management.
+* **Use the CodeRabbit logo as the profile picture** - This further ensures easy recognition. You can download our logo from [here](/img/integrations/logo.svg "download").
+
+#### Key Points to Remember
+
+* Personal access tokens have expiration dates. Ensure the expiration date covers the duration of your intended use of the CodeRabbit app.
+* Code reviews will be attributed to the owner of the personal access token.
+* If the personal access token expires, you can add a new one via the CodeRabbit UI:
+  * Navigate to the "AzureDevOps User" page in the sidebar.
+  * Add the new token and click save.
+
+### Generating a Personal Access Token
+
+Azure DevOps provides an option to generate a personal access token for a user. Follow these steps to generate the token:
+
+1. Log in as the user intended for CodeRabbit reviews.
+2. Next to your avatar on the headers right side is a settings icon, click it.
+3. Choose "Personal Access Tokens"
+4. Click "New Token"
+5. Select the organization you want to use the token with or select "All accessible organizations."
+6. Enter a name and an expiry date for the token.
+7. We need read & write access to "Work Items" & "Code" to post reviews on pull requests.
+8. Click "Create"
