```console
$ stern --namespace hb heart

Templates and values.yaml is mostly similar to stable/filebeat's.
The main difference is `config:` in values.yaml, which directly reflects heartbeat's own configuration file.
Other changelog:
- Include the configuration table in README
- Include the commented-out elasticsearch output to support common use-cases
