+- https://registry.terraform.io/providers/vultr/vultr/latest/docs/resources/server
+- https://www.vultr.com/api/
+
+## How to
+
+Assuming you have terraform installed, first you'll need to install the provider:
+
+```
+mkdir -p $GOPATH/src/github.com/vultr; cd $GOPATH/src/github.com/vultr
+git clone [email protected]:vultr/terraform-provider-vultr.git
+cd $GOPATH/src/github.com/vultr/terraform-provider-vultr
+make build
+make install
+```
+
+To fill out the terraform resource, these may come in handy:
+
+- List OSs
+    ```
+    curl -s "https://api.vultr.com/v1/os/list" | jq
+    ```
+- List configured SSH key IDs
+    ```
+    curl -s -H 'API-Key: xxx' https://api.vultr.com/v1/sshkey/list | jq
+    ```
+- List region IDs
+    ```
+    curl -s  https://api.vultr.com/v1/regions/list | jq
+    ```
+- List plans
+    ```
+    curl -s  https://api.vultr.com/v1/plans/list | jq
+    ```
+
+Finally, create your `main.tf`
+
+```
+resource "vultr_server" "box" {
+    plan_id = "203"
+    region_id = "1"
+    os_id = "270"
+    label = "test"
+    tag = "test-tag"
+    hostname = "test"
+    enable_ipv6 = true
+    auto_backup = false
+    ssh_key_ids = var.vultr_ssh_key_id # provided in secrets.tf
+}
+
+# print out the IP
+output "Box_PublicIP" {
+    value = vultr_server.box[*].main_ip
+}
+```
+
+`secrets.tf`:
+
+```
+provider "vultr" {
+  api_key = "xxx"
+  rate_limit = 700
+  retry_limit = 3
+}
+
+variable "vultr_ssh_key_id" {
+    description = "vultr ssh key id"
+    default = [ "xxx" ]
+}
+```
+
+Hit it:
+
+```
+tf apply -auto-approve
+```
