+This command is meant to be used as a kustomize exec plugin.
+
+The command reads the configuration file CONFIG passed as a first argument and
+determines a particular plugin to execute. Additional arguments may be passed
+to this command and can be used by the particular plugin.
+
+CONFIG must be a structured kubernetes manifest (i.e. resource) and must have
+'apiVersion' and 'kind' keys. If the appropriate plugin was not found, the
+command returns an error.
+
+Usage:
+  plugin CONFIG [ARGS] [flags]
+
+Examples:
+
+# Perform a replacement on a deployment. Prior to running this command,
+# the file '/tmp/replacement.yaml' should be created as follows:
+---
+apiVersion: airshipit.org/v1alpha1
+kind: ReplacementTransformer
+metadata:
+  name: notImportantHere
+replacements:
+- source:
+    value: nginx:newtag
+  target:
+    objref:
+      kind: Deployment
+    fieldrefs:
+    - spec.template.spec.containers[name=nginx-latest].image
+
+# The replacement can then be performed. Output defaults to stdout.
+airshipctl document plugin /tmp/replacement.yaml
