 ### Add secrets to your repository
 
 We'll add the service principal details as secrets in our repository. Go to your repository in GitHub, and navigate to `Settings` -> `Secrets`. Add the following secrets:
 
+- `DAGSTER_CLOUD_API_TOKEN`: An agent token. For more details see [Managing agent tokens](/dagster-plus/account/managing-user-agent-tokens#managing-agent-tokens).
 - `AZURE_CLIENT_ID`: The `appId` from the service principal JSON object.
 - `AZURE_CLIENT_SECRET`: The `password` from the service principal JSON object.

+Edit the `dagster_cloud.yaml` file in the root of your repository. Update the `build` section to use the Azure Container Registry, and provide an image name specific to the code location. This must match the registry and image name used in the previous step.

 ### Push and run the workflow
 
 Now, commit and push the changes to your repository. The GitHub Actions workflow should run automatically. You can check the status of the workflow in the `Actions` tab of your repository.
