+## Installation
+
+Jeff Geerling on YouTube made a video about the installation of this chart:
+
+[![Jeff Geerling on YouTube](https://img.youtube.com/vi/IafVCHkJbtI/0.jpg)](https://youtu.be/IafVCHkJbtI?t=2655)
+
+### Add Helm repository
+
+```shell
+helm repo add mojo2600 https://mojo2600.github.io/pihole-kubernetes/
+helm repo update
+```
+
+### Configure the chart
+
+The following items can be set via `--set` flag during installation or configured by editing the `values.yaml` directly.
+
+#### Configure the way how to expose pihole service:
+
+- **Ingress**: The ingress controller must be installed in the Kubernetes cluster.
+- **ClusterIP**: Exposes the service on a cluster-internal IP. Choosing this value makes the service only reachable from within the cluster.
+- **LoadBalancer**: Exposes the service externally using a cloud provider’s load balancer.
+
+## My settings in values.yaml
+
+```console
+dnsmasq:
+  customDnsEntries:
+    - address=/nas/192.168.178.10
+
+  customCnameEntries:
+    - cname=foo.nas,nas
+
+persistentVolumeClaim:
+  enabled: true
+
+serviceWeb:
+  loadBalancerIP: 192.168.178.252
+  annotations:
+    metallb.universe.tf/allow-shared-ip: pihole-svc
+  type: LoadBalancer
+
+serviceDns:
+  loadBalancerIP: 192.168.178.252
+  annotations:
+    metallb.universe.tf/allow-shared-ip: pihole-svc
+  type: LoadBalancer
+```
+
+## Configuring Upstream DNS Resolvers
+
+By default, `pihole-kubernetes` will configure pod DNS automatically to use Google's `8.8.8.8` nameserver for upstream
+DNS resolution. You can configure this, or opt-out of pod DNS configuration completely.
+
+### Changing The Upstream DNS Resolver
+
+For example, to use Cloudflare's resolver:
+
+```yaml
+podDnsConfig:
+  enabled: true
+  policy: "None"
+  nameservers:
+  - 127.0.0.1
+  - 1.1.1.1
+```
+
+### Disabling Pod DNS Configuration
+
+If you have other DNS policy at play (for example, when running a service mesh), you may not want to have
+`pihole-kubernetes` control this behavior. In that case, you can disable DNS configuration on `pihole` pods:
+
+```yaml
+podDnsConfig:
+  enabled: false
+```
+
+## Upgrading
+
+### To 2.0.0
+
+This version splits the DHCP service into its own resource and puts the configuration to `serviceDhcp`.
+
+**If you have not changed any configuration for `serviceDns`, you don’t need to do anything.**
+
+If you have changed your `serviceDns` configuration, **copy** your `serviceDns` section into a new `serviceDhcp` section.
+
+### To 1.8.22
+
+To enhance compatibility for Traefik, we split the TCP and UDP service into Web and DNS. This means, if you have a dedicated configuration for the service, you have to
+update your `values.yaml` and add a new configuration for this new service.
+
+Before (In my case, with metallb):
+```
+serviceTCP:
+  loadBalancerIP: 192.168.178.252
+  annotations:
+    metallb.universe.tf/allow-shared-ip: pihole-svc
+
+serviceUDP:
+  loadBalancerIP: 192.168.178.252
+  annotations:
+    metallb.universe.tf/allow-shared-ip: pihole-svc
+```
+
+After:
+```
+serviceWeb:
+  loadBalancerIP: 192.168.178.252
+  annotations:
+    metallb.universe.tf/allow-shared-ip: pihole-svc
+
+serviceDns:
+  loadBalancerIP: 192.168.178.252
+  annotations:
+    metallb.universe.tf/allow-shared-ip: pihole-svc
+```
+
+Version 1.8.22 has switched from the deprecated ingress api `extensions/v1beta1` to the go forward version `networking.k8s.io/v1`. This means that your cluster must be running 1.19.x as this api is not available on older versions. If necessary to run on an older Kubernetes Version, it can be done by modifying the ingress.yaml and changing the api definition back. The backend definition would also change from:
+
+```
+            backend:
+              service:
+                name: \{\{ $serviceName \}\}
+                port:
+                  name: http
+```
+to:
+```
+            backend:
+              serviceName: \{\{ $serviceName \}\}
+              servicePort: http
+```
+
+## Uninstallation
+
+To uninstall/delete the `my-release` deployment (NOTE: `--purge` is default behaviour in Helm 3+ and will error):
+
+```bash
+helm delete --purge my-release
+```
+
+## Configuration
+
+The following table lists the configurable parameters of the pihole chart and the default values.
+
+{{ template "chart.valuesSection" . }}
+
+{{ template "chart.maintainersSection" . }}
+
+## Remarks
+
+### MetalLB 0.8.1+
+
+pihole seems to work without issue in MetalLB 0.8.1+
+
+### MetalLB 0.7.3
+
+MetalLB 0.7.3 has a bug, where the service is not announced anymore, when the pod changes (e.g. update of a deployment). My workaround is to restart the `metallb-speaker-*` pods.
