+### Using helm chart
+
+[Helm](https://helm.sh) must be installed to use the charts.  Please refer to
+Helm's [documentation](https://helm.sh/docs) to get started.
+
+Once Helm has been set up correctly, add the repo as follows:
+
+  helm repo add vault-autounseal https://camaeel.github.io/vault-autounseal
+
+If you had already added this repo earlier, run `helm repo update` to retrieve
+the latest versions of the packages.  You can then run `helm search repo
+vault-autounseal` to see the charts.
+
+To install the vault-autounseal chart:
+
+    helm install vault-autounseal vault-autounseal/vault-autounseal --set=settings.vault_url=http://vault.vault:8200
+
+To uninstall the chart:
+
+    helm delete vault-autounseal

+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

+# 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.
