+## Globs in Kustomization Files
+
+Kustomize wants to support the best practice of storing one's
+entire configuration in a version control system.
+
+Globbing the local file system for files not explicitly
+declared in the kustomization file at `kustomize build` time
+would violate that goal.
+
+Allowing globbing in a kustomization file would also introduce
+the same problems as allowing globbing in [java import]
+declarations or BUILD/Makefile dependency rules.
+
+Kustomize will instead provide kustomization file editting
+commands that accept globbed arguments, expand them at _edit
+time_ relative to the local file system, and store the resulting
+explicit names into the kustomization file.
+
+In this way the resources, patches and bases used at _build time_
+remain explicitly declared in version control.
