+The UI talks to the K8s API server as well as the Postgres Operator [REST API](developer.md#debugging-the-operator).
+K8s API server URLs are loaded from the machine's kubeconfig environment by
+default. Alternatively, a list can also be passed when starting the Python
+application with the `--cluster` option.
+
+The Operator API endpoint can be configured via the `OPERATOR_API_URL`
+environment variables in the [deployment manifest](../ui/manifests/deployment.yaml#L40).
+You can also expose the operator API through a [service](../manifests/api-service.yaml).
+Some displayed options can be disabled from UI using simple flags under the
+`OPERATOR_UI_CONFIG` field in the deployment.
+
+### Deploy the UI on K8s
+
+Now, apply all manifests from the `ui/manifests` folder to deploy the Postgres
+Operator UI on K8s. Replace the image tag in the deployment manifest if you
+want to test the image you've built with `make docker`. Make sure the pods for

+
+## Deploy the operator UI
+
+In the following paragraphs we describe how to access and manage PostgreSQL
+clusters from the command line with kubectl. But it can also be done from the
+browser-based [Postgres Operator UI](operator-ui.md). Before deploying the UI
+make sure the operator is running and its REST API is reachable through a
+[K8s service](../manifests/api-service.yaml). The URL to this API must be
+configured in the [deployment manifest](../ui/manifests/deployment.yaml#L43)
+of the UI.
+
+To deploy the UI simply apply all its manifests files or use the UI helm chart:
+
+```bash
+# manual deployment
+kubectl apply -f ui/manifests/
+
+# or helm chart
+helm install postgres-operator-ui ./charts/postgres-operator-ui
+```
+
+Like with the operator, check if the UI pod gets into `Running` state:
+
+```bash
+# if you've created the operator using yaml manifests
+kubectl get pod -l name=postgres-operator-ui
+
+# if you've created the operator using helm chart
+kubectl get pod -l app.kubernetes.io/name=postgres-operator-ui
+```
+
+You can now access the web interface by port forwarding the UI pod (mind the
+label selector) and enter `localhost:8081` in your browser:
+
+```bash
+kubectl port-forward "$(kubectl get pod -l name=postgres-operator-ui --output='name')" 8081
+```
+
+Available option are explained in detail in the [UI docs](operator-ui.md).
+
+## Create a Postgres cluster
+
+If the operator pod is running it listens to new events regarding `postgresql`
+resources. Now, it's time to submit your first Postgres cluster manifest.
+
+```bash
 # create a Postgres cluster
 kubectl create -f manifests/minimal-postgres-manifest.yaml
