-#### Troubleshooting
+### Creating secret for deployapp test
+
+The e2e test that runs click-to-deploy app will test deploying kubeflow to a cluter
+under project kubeflow-ci-deployment.
+So it needs to know a clientID and secret of that project.
+Check out this [page](https://pantheon.corp.google.com/apis/credentials?project=kubeflow-ci-deployment&folder&organizationId=714441643818)
+and look for client ID called deployapp-test-client.
+
+```
+kubectl create secret generic --namespace=${NAMESPACE} kubeflow-oauth --from-literal=client_id=${CLIENT_ID} --from-literal=client_secret=${CLIENT_SECRET}
+```
