-To more cleanly handle cases where desired functionality would require complex duplication of Terraform resources (i.e. [PR 51](https://github.com/terraform-google-modules/terraform-google-kubernetes-engine/pull/51)), this repository is divided into multiple submodules. To ensure backwards compatibility with the module before this change, the root module of the repository defers to the [`public-cluster`](./modules/public-cluster) submodule.
+To more cleanly handle cases where desired functionality would require complex duplication of Terraform resources (i.e. [PR 51](https://github.com/terraform-google-modules/terraform-google-kubernetes-engine/pull/51)), this repository is largely generated from the [`autogen`](./autogen) directory.
 
-The following submodules currently exist:
-
-- [`public-cluster`](./modules/public-cluster), which creates a GKE cluster with its nodes and endpoint publicly accessible.
-
-Submodules and the root module are generated by running `make generate`. Changes to this repository should be made in the [`autogen`](./autogen) directory if they are intended to propagate to all submodules.
