+# Bootstrap Module
+
+This [Terraform][] [module][] manages [libvirt][] resources only needed during cluster bootstrapping.
+It uses [implicit provider inheritance][implicit-provider-inheritance] to access the [libvirt provider][libvirt-provider].
+
+## Example
+
+Set up a `main.tf` with:
+
+```hcl
+provider "libvirt" {
+  uri = "qemu:///system"
+}
+
+resource "libvirt_network" "example" {
+  name   = "example"
+  mode   = "none"
+  domain = "example.com"
+  addresses = ["192.168.0.0/24"]
+}
+
+resource "libvirt_volume" "example" {
+  name   = "example"
+  source = "file:///path/to/example.qcow2"
+}
+
+module "bootstrap" {
+  source = "github.com/openshift/installer//data/data/libvirt/bootstrap"
+
+  addresses      = ["192.168.0.1"]
+  base_volume_id = "${libvirt_volume.example.id}"
+  cluster_id     = "my-cluster"
+  ignition       = "{\"ignition\": {\"version\": \"2.2.0\"}}",
+  network_id     = "${libvirt_network.example.id}"
+}
+```
+
+Then run:
+
+```console
+$ terraform init
+$ terraform plan
+```
