+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
+type: application
+
+# This is the chart version. This version number should be incremented each time you make changes
+# to the chart and its templates, including the app version.
+version: 1.3.11
+
+# This is the version number of the application being deployed. This version number should be
+# incremented each time you make changes to the application.

+# Telegraf-operator Helm chart
+
+> Default installation expects `cert-manager` to be running in the cluster.
+
+## Prerequisites
+
+- Helm v2 or later
+- Kubernetes 1.11+ with Beta APIs enabled
+
+## Install the chart
+
+1. Add the InfluxData Helm repository:
+
+   ```bash
+   helm repo add influxdata https://helm.influxdata.com/
+   ```
+
+2. Run the following command, providing a name for your release:
+
+   ```bash
+   helm upgrade --install my-release influxdata/telegraf-operator
+   ```
+
+   > **Tip**: `--install` can be shortened to `-i`.
+
+   This command deploys Telegraf-operator on the Kubernetes cluster using the default configuration. To find parameters you can configure during installation, see [Configure the chart](#configure-the-chart).
+
+   > **Tip**: To view all Helm chart releases, run `helm list`.
+
+## Uninstall the chart
+
+To uninstall the `my-release` deployment, use the following command:
+
+```bash
+helm uninstall my-release
+```
+
+This command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configure the chart
+
+Configurable parameters, their descriptions, and their default values are stored in `values.yaml`.
+
+To configure the chart, do either of the following:
+
+- Specify each parameter using the `--set key=value[,key=value]` argument to `helm upgrade --install`. For example, use the following command:
+
+  ```bash
+  helm upgrade --install my-release \
+  --set persistence.enabled=true \
+    influxdata/telegraf-operator
+  ```
+  
+This command enables persistence.
+
+- Provide a YAML file that specifies parameter values while installing the chart. For example, use the following command:
+
+  ```bash
+  helm upgrade --install my-release -f values.yaml influxdata/telegraf-operator
+  ```
+
+  > **Tip**: Use the default [values.yaml](values.yaml).
+
+For information about running Telegraf-operator in Docker, see the [full image documentation](https://hub.docker.com/_/kapacitor/).
+
+## Contribute to the chart
+
+```shell
+helm template --namespace=telegraf-operator telegraf-operator .
+```
+
+### Test installation with Kind
+
+```shell
+kind create cluster --name=telegraf-operator-test
+kubectl config use-context kind-telegraf-operator-test
+kubectl apply -f tests/influxdb.yml
+helm install telegraf-operator .
+kubectl apply -f tests/redis.yml
+kind delete cluster --name=telegraf-operator-test
+```
+
+## Cert-manager integration 
+
+For better security there is already an integration with cert-manger >0.13 that can be enabled but you have to provide your own instalation of cert-manager in the cluster
