+# 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

+# 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
