## Installation with helm
34+
35+
Add the cluster-proportional-autoscaler Helm repository:
36+
```sh
37+
helm repo add cluster-proportional-autoscaler https://kubernetes-sigs.github.io/cluster-proportional-autoscaler
38+
helm repo update
39+
```
40+
41+
Then install a release using the chart. The [charts default values file](charts/cluster-proportional-autoscaler/values.yaml) provides some commented out examples for setting some of the values. There are several required values, but helm should fail with messages that indicate which value is missing.
42+
```sh
43+
helm upgrade --install cluster-proportional-autoscaler \
44+
cluster-proportional-autoscaler/cluster-proportional-autoscaler --values <<name_of_your_values_file>>.yaml
45+
```
