+
+NOTE - A configMap of available IPs is to be applied in order for services
+to get external IP address assigned. Please Update values.yaml with
+IP addresses before deploying
+
+Prerequisites
+-------------
+
+-  Kubernetes 1.9+
+
+Installing the Chart
+--------------------
+
+The chart can be installed as follows:
+
+```console
+$ helm install --name metallb metallb
+```
+
+The command deploys MetalLB on the Kubernetes cluster. This chart does
+not provide a default configuration; MetalLB will not act on your
+Kubernetes Services until you provide
+one. The [configuration](#configuration) section lists various ways to
+provide this configuration.
+
+Uninstalling the Chart
+----------------------
+
+To uninstall/delete the `metallb` deployment:
+
+```console
+$ helm delete metallb
+```
+
+The command removes all the Kubernetes components associated with the
+chart, but will not remove the release metadata from `helm` — this will prevent
+you, for example, if you later try to create a release also named `metallb`). To
+fully delete the release and release history, simply [include the `--purge`
+flag][helm-usage]:
+
+```console
+$ helm delete --purge metallb
+```
+
+Configuration
+-------------
+
+See `values.yaml` for configuration notes. Specify each parameter
+using the `--set key=value[,key=value]` argument to `helm
+install`. For example,
+
+```console
+$ helm install --name metallb \
+  --set rbac.create=false \
+    stable/metallb
+```
+
+The above command disables the use of RBAC rules.
+
+Alternatively, a YAML file that specifies the values for the above
+parameters can be provided while installing the chart. For example,
+
+```console
+$ helm install --name metallb -f values.yaml metallb
+```
+
+By default, this chart does not install a configuration for MetalLB, and simply
+warns you that you must follow [the configuration instructions on MetalLB's
+website][metallb-config] to create an appropriate ConfigMap.
+
+**Please note:** By default, this chart expects a ConfigMap named
+'metallb-config' within the same namespace as the chart is
+deployed. _This is different than the MetalLB documentation_, which
+asks you to create a ConfigMap in the `metallb-system` namespace, with
+the name of 'config'.
+
+For simple setups that only use MetalLB's [ARP mode][metallb-arpndp-concepts],
+you can specify a single IP range using the `arpAddresses` parameter to have the
+chart install a working configuration for you:
+
+```console
+$ helm install --name metallb \
+  --set arpAddresses=192.168.16.240/30 \
+  stable/metallb
+```
+
+If you have a more complex configuration and want Helm to manage it for you, you
+can provide it in the `config` parameter. The configuration format is
+[documented on MetalLB's website][metallb-config].
+
+```console
+$ cat values.yaml
+configInline:
+  peers:
+  - peer-address: 10.0.0.1
+    peer-asn: 64512
+    my-asn: 64512
+  address-pools:
+  - name: default
+    protocol: bgp
+    addresses:
+    - 198.51.100.0/24
+
+$ helm install --name metallb -f values.yaml metallb
+```
