+description: A Helm chart for Kubernetes
+
+# 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.
+# Versions are expected to follow Semantic Versioning (https://semver.org/)
+version: 0.1.0
+
+# This is the version number of the application being deployed. This version
number should be
+# incremented each time you make changes to the application. Versions are not
expected to
+# follow Semantic Versioning. They should reflect the version the application
is using.
+# It is recommended to use it with quotes.
+appVersion: "1.16.0"
