# 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.
