# 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
8+
# to be deployed.
9+

10+
# Library charts provide useful utilities or functions for the chart developer. They're included as
11+
# a dependency of application charts to inject those utilities and functions into the rendering
12+
# pipeline. Library charts do not define any templates and therefore cannot be deployed.

# This is the chart version. This version number should be incremented each time you make changes
