+#Alpine: A simple Helm chart
+
+Run a single pod of Alpine Linux.
+
+This example was generated using the command `helm create alpine`.
+
+The `templates/` directory contains a very simple pod resource with a
+couple of parameters.
+
+The `values.yaml` file contains the default values for the
+`alpine-pod.yaml` template.
+
+You can install this example using `helm install docs/examples/alpine`.
