 When updating a job in this repo, for example when changing the user-specified
 parameters but _not_ when changing the pipeline to be run, manually trigger
 the sqre/seeds/dm-jobs job to rebuild the interface.

+`seeds` contains a README plus a helm values file for deploying a Jenkins
+controller at SLAC. Read that README for more details.
+
+`lsst-jenkins-swarm-agent` contains a helm chart to run a Linux Jenkins Agent
+and associated containers needed for tests/package. Documentation for this has
+not yet been created (you'll need to look at the individual templates).

+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.
