-# bootkube-terraform
+# terraform-render-bootkube
 
-`bootkube-terraform` is a Terraform module that renders [bootkube](https://github.com/kubernetes-incubator/bootkube) assets, just like running the binary `bootkube render`. It aims to provide the same variable names, defaults, features, and outputs.
+`terraform-render-bootkube` is a Terraform module that renders [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube) assets for bootstrapping a Kubernetes cluster.
+
+## Audience
+
+`terraform-render-bootkube` is a low-level component of the [Typhoon](https://github.com/poseidon/typhoon) Kubernetes distribution. Use Typhoon modules to create and manage Kubernetes clusters across supported platforms. Use the bootkube module if you'd like to customize a Kubernetes control plane or build your own distribution.
 
 ## Usage
 
-Use the `bootkube-terraform` module within your existing Terraform configs. Provide the variables listed in `variables.tf` or check `terraform.tfvars.example` for examples.
+Use the module to declare bootkube assets. Check [variables.tf](variables.tf) for options and [terraform.tfvars.example](terraform.tfvars.example) for examples.
 
 ```hcl
 module "bootkube" {
-  source = "git://https://github.com/dghubble/bootkube-terraform.git?ref=SHA"
+  source = "git://https://github.com/poseidon/terraform-render-bootkube.git?ref=SHA"
 
   cluster_name = "example"
   api_servers = ["node1.example.com"]
   etcd_servers = ["node1.example.com"]
   asset_dir = "/home/core/clusters/mycluster"
-  experimental_self_hosted_etcd = false
 }
 ```
 
-Alternately, use a local checkout of this repo and copy `terraform.tfvars.example` to `terraform.tfvars` to generate assets without an existing terraform config repo.

-Generate the bootkube assets.

 ```sh
-terraform get
