 This resource is intended to be used in conjunction with a Terraform provider
 for a particular certificate authority in order to provision a new certificate.
+This is a *logical resource*, so it contributes only to the current Terraform
+state and does not create any external managed resources.
+
+~> **Compatibility Note** From Terraform 0.7.0 to 0.7.4 this resource was
+converted to a data source, and the resource form of it was deprecated. This
+turned out to be a design error since a cert request includes a random number
+in the form of the signature nonce, and so the data source form of this
+resource caused non-convergent configuration. The data source form is no longer
+supported as of Terraform 0.7.5 and any users should return to using the
+resource form.
 
 ## Example Usage
 
 ```
-data "tls_cert_request" "example" {
+resource "tls_cert_request" "example" {
     key_algorithm = "ECDSA"
     private_key_pem = "${file(\"private_key.pem\")}"
