+# submodule
+
+This repo demonstrates kustomize's ability to download git repos 
+with submodules. The following branches contain
+* main: submodule via absolute path
+* relative-submodule: submodule via relative path
+
+For the submodule accessed via a relative path, we include a random hash in the
+submodule name to avoid accessing an unintended directory in the case kustomize
+contains loader bugs (issue #5131).
