+  ## Description
+
+  A library that shall collect certain templates to reuse them among different charts.
+
+This Helm Chart is a library of reusable template, like tolerations or resources.
+Instead of defining them in other Charts multiple times, it is possible to simply include the template.
+
+The template "tpl.sleeptimer" is a simple template that can be used for Job to print our a timer.
+
+## Dependencies
+
+This chart has the following dependencies:

+
+## Values
+
+| Key | Type | Default | Description |
+|-----|------|---------|-------------|
+| nodeSelector.key | string | `"node-role.kubernetes.io/infra"` |  |
+| nodeSelector.value | string | `""` |  |
+| resources | object | `{"limits":{"cpu":8,"ephemeral-storage":500,"memory":16},"requests":{"cpu":4,"ephemeral-storage":50,"memory":8}}` | If you want to define resources <br /> Example include: {{- if .Values.resources }} {{ include "tpl.resources" .Values.resources  | indent 0 }} {{- end }} |
+| tolerations | list | `[{"effect":"NoSchedule","key":"infra","operator":"Equal","tolerationSeconds":600,"value":"reserved"},{"effect":"NoSchedule","key":"infra","operator":"Equal","tolerationSeconds":600,"value":"reserved"}]` | If you want this component to only run on specific nodes, you can configure tolerations of tainted nodes. <br /> Example include: {{- if .Values.tolerations }} {{ include "tpl.tolerations" .Values.tolerations  | indent 0 }} {{- end }} |
+
+## Example values
+
+```yaml
+---
+# Examples values file
+
+tolerations:
+  - effect: NoSchedule
+    key: infra
+    operator: Equal
+    value: reserved
+    tolerationSeconds: 600
+  - effect: NoSchedule
+    key: infra
+    operator: Equal
+    value: reserved
+    tolerationSeconds: 600
+
+resources:
+  requests:
+    cpu: 4
+    memory: 8
+    ephemeral-storage: 50
+  limits:
+    cpu: 8
+    memory: 16
+    ephemeral-storage: 500
+
+nodeSelector:
+  key: node-role.kubernetes.io/infra
+  value: ''
+```
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```console
+helm install my-release repo/<chart-name>>
+```
+
+The command deploys the chart on the Kubernetes cluster in the default configuration.
+
+## Uninstalling the Chart
+
+To uninstall/delete the my-release deployment:
+
+```console
+helm delete my-release
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
