+
+### Migrating from stable/kube-state-metrics and kubernetes/kube-state-metrics
+
+You can upgrade in-place:
+
+1. [get repo info](#get-repo-info)
+1. [upgrade](#upgrading-chart) your existing release name using the new chart repo
+
+
+## Upgrading to v3.0.0
+
+v3.0.0 includes kube-state-metrics v2.0, see the [changelog](https://github.com/kubernetes/kube-state-metrics/blob/release-2.0/CHANGELOG.md) for major changes on the application-side.

+kube-state-metrics is a simple service that listens to the Kubernetes API server and generates metrics about the state of the objects.
+The exposed metrics can be found here:
+https://github.com/kubernetes/kube-state-metrics/blob/master/docs/README.md#exposed-metrics
+
+The metrics are exported on the HTTP endpoint /metrics on the listening port.
+In your case, {{ template "kube-state-metrics.fullname" . }}.{{ template "kube-state-metrics.namespace" . }}.svc.cluster.local:{{ .Values.service.port }}/metrics
+
+They are served either as plaintext or protobuf depending on the Accept header.
+They are designed to be consumed either by Prometheus itself or by a scraper that is compatible with scraping a Prometheus client endpoint.
