-# bootkube-terraform
+# terraform-render-bootkube
 
-`bootkube-terraform` is Terraform module that renders [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube) bootstrapping assets. It functions as a low-level component of the [Typhoon](https://github.com/poseidon/typhoon) Kubernetes distribution.
+`terraform-render-bootkube` is a Terraform module that renders [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube) assets for bootstrapping a Kubernetes cluster.
 
-The module provides many of the same variable names, defaults, features, and outputs as running `bootkube render` directly.
+## 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 [Typhoon](https://github.com/poseidon/typhoon) to create and manage Kubernetes clusters in different environments. Use `bootkube-terraform` if you require low-level customizations to the control plane or wish to build your own distribution.
-
-Add the `bootkube-terraform` module alongside 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.
+Generate the assets.
 
 ```sh
-terraform get
+terraform init
+terraform get --update
 terraform plan
 terraform apply
 ```
 
+Find bootkube assets rendered to the `asset_dir` path. That's it.
+

-Compare assets. The only diffs you should see are TLS credentials.
+Compare assets. Rendered assets may differ slightly from bootkube assets to reflect decisions made by the [Typhoon](https://github.com/poseidon/typhoon) distribution.
