-Helm chart](#configure-the-netdata-helm-chart) to suit your cluster's particular setup.
+You've now installed Netdata on your Kubernetes cluster. Next, it's time to opt-in and enable the powerful Kubernetes
+dashboards available in Netdata Cloud.
 
-## Configure the Netdata Helm chart
+## Claim your Kubernetes cluster to Netdata Cloud
 
-Read up on the various configuration options in the [Helm chart
-documentation](https://github.com/netdata/helmchart#configuration) to see if you need to change any of the options based
-on your cluster's setup.
+To start [Kubernetes monitoring](https://learn.netdata.cloud/docs/cloud/visualize/kubernetes/), you must first
+[claim](/claim/README.md) your Kubernetes cluster to [Netdata Cloud](https://app.netdata.cloud). Claiming securely
+connects your Kubernetes cluster to stream metrics data to Netdata Cloud, enabling Kubernetes-specific visualizations
+like the health map and time-series composite charts.
 
-To change a setting, use the `--set` or `--values` arguments with `helm install`, for the initial deployment, or `helm upgrade` to upgrade an existing deployment. 
+First, find your claiming script in Netdata Cloud by clicking on your Space's dropdown, then **Manage your Space**.
+Click the **Nodes** tab to reveal the `netdata-claim.sh` script for your Space in Netdata Cloud. You need the `TOKEN`
+and `ROOM` values.
 
-```bash
-helm install --set a.b.c=xyz netdata netdata/netdata
-helm upgrade --set a.b.c=xyz netdata netdata/netdata
-```
-
-For example, to change the size of the persistent metrics volume on the parent node:
+Next, create a file called `override.yml`.
 
 ```bash
-helm install --set parent.database.volumesize=4Gi netdata netdata/netdata
-helm upgrade --set parent.database.volumesize=4Gi netdata netdata/netdata
+touch override.yml
 ```
 
-### Configure service discovery
-
-As mentioned in the introduction, Netdata has a [service discovery
-plugin](https://github.com/netdata/agent-service-discovery/#service-discovery) to identify compatible pods and collect
-metrics from the service they run. The Netdata Helm chart installs this service discovery plugin into your k8s cluster.
-
-Service discovery scans your cluster for pods exposed on certain ports and with certain image names. By default, it
-looks for its supported services on the ports they most commonly listen on, and using default image names. Service
-discovery currently supports [popular
-applications](https://github.com/netdata/helmchart#service-discovery-and-supported-services), plus any endpoints covered
-by our [generic Prometheus collector](https://learn.netdata.cloud/docs/agent/collectors/go.d.plugin/modules/prometheus).
-
-If you haven't changed listening ports, image names, or other defaults, service discovery should find your pods, create
-the proper configurations based on the service that pod runs, and begin monitoring them immediately after deployment.
+Paste the following into your `override.yml` file, replacing instances of `ROOM` and `TOKEN` with those from the
+claiming script from Netdata Cloud. These settings claim your `parent`/`child` nodes to Netdata Cloud and store more
+metrics in the nodes' time-series databases.
+
+```yaml
+parent:
+  claiming:
+    enabled: true
+    token: "TOKEN"
+    rooms: "ROOM"
+
+child:
+  claiming:
+    enabled: true
+    token: "TOKEN"
+    rooms: "ROOM"
+  configs:
+    netdata:
+      data: |
+        [global]
+          memory mode = ram
+          history = 3600
+        [health]
+          enabled = no
+```
 
-However, if you have changed some of these defaults, you need to copy a file from the Netdata Helm chart repository,
-make your edits, and pass the changed file to `helm install`/`helm upgrade`.
+> ❗ These override settings, along with the Helm chart's defaults, will retain an hour's worth of metrics (`history =
+> 3600`, or `3600 seconds`) on each child node. Based on your metrics retention needs, and the resources available on
+> your cluster, you may want to increase the `history` setting.
 
-First, copy the file to your administrative system.
+Apply these new settings:
 
 ```bash
-curl https://raw.githubusercontent.com/netdata/helmchart/master/charts/netdata/sdconfig/child.yml -o child.yml
+helm upgrade -f override.yml netdata netdata/netdata
 ```
 
-Edit the new `child.yml` file according to your needs. See the [Helm chart
-configuration](https://github.com/netdata/helmchart#configuration) and the file itself for details. 
+The cluster terminates the old pods and creates new ones with the proper persistence and claiming configuration. You'll
+see your nodes, containers, and pods appear in Netdata Cloud in a few seconds.
 
-You can then run `helm install`/`helm upgrade` with the `--set-file` argument to use your configured `child.yml` file
-instead of the default, changing the path if you copied it elsewhere.

-```bash
-helm install --set-file sd.child.configmap.from.value=./child.yml netdata netdata/netdata
-helm upgrade --set-file sd.child.configmap.from.value=./child.yml netdata netdata/netdata

-Your configured service discovery is now pushed to your cluster.
+## Configure your Netdata monitoring deployment
 
-## Access the Netdata dashboard
+Read up on the various configuration options in the [Helm chart
+documentation](https://github.com/netdata/helmchart#configuration) if you need to tweak your Kubernetes monitoring.
 
-Accessing the Netdata dashboard itself depends on how you set up your k8s cluster and the Netdata Helm chart. If you
-installed the Helm chart with the default `service.type=ClusterIP`, you will need to forward a port to the parent pod.
+Your first option is to create an `override.yml` file, if you haven't created one already for
+[claiming](#claim-your-kubernetes-cluster-to-netdata-cloud), then apply the new configuration to your cluster with `helm
+upgrade`.
 
 ```bash
-kubectl port-forward netdata-parent-0 19999:19999 
+helm upgrade -f override.yml netdata netdata/netdata
 ```
 
-You can now access the dashboard at `http://CLUSTER:19999`, replacing `CLUSTER` with the IP address or hostname of your
-k8s cluster.
-
-If you set up the Netdata Helm chart with `service.type=LoadBalancer`, you can find the external IP for the load
-balancer with `kubectl get services`, under the `EXTERNAL-IP` column.
+If you want to change only a single setting, use the `--set` argument with `helm upgrade`. For example, to change the
+size of the persistent metrics volume on the parent node:
 
 ```bash
-kubectl get services
-NAME                 TYPE           CLUSTER-IP       EXTERNAL-IP    PORT(S)              AGE
-cockroachdb          ClusterIP      None             <none>         26257/TCP,8080/TCP   46h
-cockroachdb-public   ClusterIP      10.245.148.233   <none>         26257/TCP,8080/TCP   46h
-kubernetes           ClusterIP      10.245.0.1       <none>         443/TCP              47h
-netdata              LoadBalancer   10.245.160.131   203.0.113.0    19999:32231/TCP      74m
+helm upgrade --set parent.database.volumesize=4Gi netdata netdata/netdata
 ```
 
-In the above example, access the dashboard by navigating to `http://203.0.113.0:19999`.
-
-## Claim a Kubernetes cluster's parent pod
-
-You can [claim](/claim/README.md) a cluster's parent Netdata pod to see its real-time metrics alongside any other nodes
-you monitor using [Netdata Cloud](https://app.netdata.cloud).
+### Configure service discovery
 
-> Netdata Cloud does not currently support claiming child nodes because the Helm chart does not allocate a persistent
-> volume for them.
+Netdata's [service discovery](https://github.com/netdata/agent-service-discovery/#service-discovery), installed as part
+of the Helm chart installation, finds what services are running in a cluster's containers and automatically collects
+service-level metrics from them.
 
-Ensure persistence is enabled on the parent pod by running the following `helm upgrade` command.
+Service discovery supports [popular applications](https://github.com/netdata/helmchart#applications) and [Prometheus
+endpoints](https://github.com/netdata/helmchart#prometheus-endpoints).
 
-```bash
-helm upgrade \
-  --set parent.database.persistence=true \
-  --set parent.alarms.persistence=true \
-  netdata netdata/netdata
-```
+If your cluster runs services on non-default ports or uses non-default names, you may need to configure service
+discovery to start collecting metrics from your services. You have to edit the default ConfigMap that is shipped with
+the Helmchart and deploy that to your cluster.
 
-Next, find your claiming script in Netdata Cloud by clicking on your Space's dropdown, then **Manage your Space**. Click
-the **Nodes** tab. Netdata Cloud shows a script similar to the following:
+First, copy the default file to your administrative system.
 
 ```bash
-sudo netdata-claim.sh -token=TOKEN -rooms=ROOM1,ROOM2 -url=https://app.netdata.cloud
+curl https://raw.githubusercontent.com/netdata/helmchart/master/charts/netdata/sdconfig/child.yml -o child.yml
 ```
 
-You will need the values of `TOKEN` and `ROOM1,ROOM2` for the command, which sets `parent.claiming.enabled`,
-`parent.claiming.token`, and `parent.claiming.rooms` to complete the parent pod claiming process.
+Edit the new `child.yml` file according to your needs. See the [Helm chart
+configuration](https://github.com/netdata/helmchart#configuration) and the file itself for details.
 
-Run the following `helm upgrade` command after replacing `TOKEN` and `ROOM1,ROOM2` with the values found in the claiming
-script from Netdata Cloud. The quotations are required.
+You can then run `helm upgrade` with the `--set-file` argument to use your configured `child.yml` file instead of the
+default, changing the path if you copied it elsewhere.
 
 ```bash
-helm upgrade \
-  --set parent.claiming.enabled=true \
-  --set parent.claiming.token="TOKEN" \
-  --set parent.claiming.rooms="ROOM1,ROOM2" \
-  netdata netdata/netdata
+helm upgrade --set-file sd.child.configmap.from.value=./child.yml netdata netdata/netdata
 ```
 
-The cluster terminates the old parent pod and creates a new one with the proper claiming configuration. You can see your
-parent pod in Netdata Cloud after a few moments. You can now [build new
-dashboards](https://learn.netdata.cloud/docs/cloud/visualize/dashboards) using the parent pod's metrics or run [Metric
-Correlations](https://learn.netdata.cloud/docs/cloud/insights/metric-correlations) to troubleshoot anomalies.

+Now that you pushed an edited ConfigMap to your cluster, service discovery should find and set up metrics collection
+from your non-default service.
