+# Logz.io forked chart
+The `kube-state-metrics` helm chart was forked in order to divide the load of `pods` metrics collection by creating a daemonset with `daemonset.enabled` flag which is enabled by default. 
+The rest of the resources metrics will be collected by the deployment pod.
+
+## Disable DaemonSet Pods Metrics Sharding 
+
+```console
+helm install logzio-kube-state-metrics logzio-helm/kube-state-metrics --set daemonset.enabled=false
+```
+
+Un-comment the `pods` metrics in the `collectors` configuraiton.
+
+# kube-state-metrics Helm Chart 
+
+Installs the [kube-state-metrics agent](https://github.com/kubernetes/kube-state-metrics).
+
+
+## Get Repo Info
+
+```console
+helm repo add logzio-helm https://logzio.github.io/logzio-helm
+helm repo update
+```
+
+_See [helm repo](https://helm.sh/docs/helm/helm_repo/) for command documentation._
+
+## Install Chart
+
+```console
+helm install logzio-kube-state-metrics logzio-helm/kube-state-metrics [flags]
+```
+
+_See [configuration](#configuration) below._
+
+_See [helm install](https://helm.sh/docs/helm/helm_install/) for command documentation._
+
+## Uninstall Chart
+
+```console
+helm uninstall logzio-kube-state-metrics
+```
+
+This removes all the Kubernetes components associated with the chart and deletes the release.
+
+_See [helm uninstall](https://helm.sh/docs/helm/helm_uninstall/) for command documentation._
+
+## Upgrading Chart
+
+```console
+helm upgrade logzio-kube-state-metrics logzio-helm/kube-state-metrics [flags]
+```
+
+_See [helm upgrade](https://helm.sh/docs/helm/helm_upgrade/) for command documentation._
+
+### 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.
+
+The upgraded chart now the following changes:
+* Dropped support for helm v2 (helm v3 or later is required)
+* collectors key was renamed to resources
+* namespace key was renamed to namespaces
+
+
+## Configuration
+
+See [Customizing the Chart Before Installing](https://helm.sh/docs/intro/using_helm/#customizing-the-chart-before-installing). To see all configurable options with detailed comments:
+
+```console
+helm show values logzio-helm/kube-state-metrics
+```
+
+You may also run `helm show values` on this chart's [dependencies](#dependencies) for additional options.
