+# 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.

+# This is the chart version. This version number should be incremented each time you make changes

+# Versions are expected to follow Semantic Versioning (https://semver.org/)

+**WARNING: THIS CHART IS NOT MEANT TO BE INSTALLED DIRECTLY**
+
+This is a [Helm Library Chart](https://helm.sh/docs/topics/library_charts/#helm). It's purpose is for grouping common logic between the k8s@home charts. 
+
+Since a lot of charts follow the same pattern this library was built to reduce maintenance cost between the charts that use it and try achieve a goal of being DRY.
+
+## Introduction
+
+This chart provides common template helpers which can be used to develop new charts using [Helm](https://helm.sh) package manager.
