+```bash
+helm upgrade --namespace vl --install vl vm/victoria-logs-single -f vl.yaml

 ## Configure logs forwarding
 
-We need to create a `ClusterLogForwarder` resource to forward logs from the OpenShift Logging operator to VictoriaLogs.
+Cluster logging operator uses `ClusterLogForwarder` resource for logs forwarding configuration.
 
-Run the following command to create the resource file:
-
-```shell
-cat <<EOF > vl-forwarder.yml
+Here is an example configuration to forward all cluster logs to VictoriaLogs:
+```yaml
 apiVersion: observability.openshift.io/v1
 kind: ClusterLogForwarder

-Alternatively, you can configure log forwarding in the OpenShift web console. To do this:
-1. Navigate to **Operators** tab
-2. Click on **Installed Operators**.
-3. Find **Red Hat OpenShift Logging**
-4. Navigate to **ClusterLogForwarders**.
-5. Click on **Create ClusterLogForwarder**.

-## Verify logs ingestion
-
-We can verify that logs are being collected using the VictoriaLogs VMUI.
-
-First, find the service name for the VMUI with:
-
-```shell
-kubectl get svc -n vl -l app.kubernetes.io/instance=vl
-```
-
-You should get a result similar to this. Note the name of the service:
-
-```text
-NAME                             TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)    AGE
-vl-victoria-logs-single-server   ClusterIP   None         <none>        9428/TCP   113s
-```
-
-Then, port-forward the VMUI service console with:
-
-```shell
-kubectl -n vl port-forward svc/vl-victoria-logs-single-server 9428:9428
-```
-
-Open your browser in `http://localhost:9428/select/vmui/#/overview` and verify that logs are being collected. This overview page shows the number of log entries being consumed in real time.

-
-You can query your logs in the **Query** tab, found in `http://localhost:9428/select/vmui`. 
-You can filter streams on the left side pane to filter logs and use [LogsQL](https://docs.victoriametrics.com/victorialogs/logsql/) to search for entries. Note that logs will have `log_type` attached to them to distinguish between different types of logs.
