+## Create an Azure Application
+
+Log into your Azure DevOps account or create a new one, and ensure you have a project set up.
+
+Make sure the organization has third-party access via OAuth enabled in the organization settings.

+
+
+To use the Azure DevOps integration you'll need to create an application.
+
+To start, you will need access to a [Microsoft Entra Admin Portal](https://entra.microsoft.com/#home)
+
+![Register App](./register-app.png)
+
+
+When configuring the app, use the following values:
+
+| Setting                         | Value                                                                                              |
+| ------------------------------- | -------------------------------------------------------------------------------------------------- |
+| Supported account types         | Accounts in any organizational directory |
+| Redirect URI                    | `{YOUR_DOMAIN}/extensions/vsts/setup`                                                              |
+
+<Note>
+
+Take note of your App ID as we'll need it later.
+![App ID](./app-id.png)
+
+</Note>
+
+Next go to Manager -> API Permissions to add the following permissions:
+* Azure DevOps (`vso.code`, `vso.graph`, `vso.work_item`, `vso.service_endpoint`)
+* Microsoft Graph (`User.Read`) (This should be added by default)
+
+![Permissions](./perms.png)
+
+Go to the "Certificates & secrets" tab and create a new client secret. Make sure you copy the secret as we'll need it later.
+
+![Client Secret](./client-secret.png)
+
+Add the App ID and Client Secret to `devlocal.py` like this:
+
+```python
+# Azure DevOps #
+SENTRY_OPTIONS["vsts_new.client-id"] = your-app-id
+SENTRY_OPTIONS["vsts_new.client-secret"] = your-client-secret
+```
+
+You can also add the App ID and Client Secret to `config.yml` like this:
+
+```yml
+# Azure DevOps #
+vsts_new.client-id: your-app-id
+vsts_new.client-secret: your-client-secret
+```
+
+You will also need to enable the feature flag to use the new Azure DevOps integration.
+Enable the `migrate-azure-devops-integration` feature flag in your organization.
+Add the following to your `devlocal.py` file:
+
+```python
+SENTRY_FEATURES["organizations:migrate-azure-devops-integration"] = True
+```
+
+<Alert title="Feature Flag" level="info">
+
+This is a temporary measure until we fully migrate to the new Azure DevOps integration and remove references to the old one.
+
+</Alert>
+
+Follow our [documentation on installing and configuring the Azure DevOps integration](https://docs.sentry.io/organization/integrations/source-code-mgmt/azure-devops/) to finish installation and use the integration.
