 Thank you for opening an issue. Please note that we try to keep the Terraform issue tracker reserved for bug reports and feature requests. For general usage questions, please see: https://www.terraform.io/community.html.
 
+If your issue relates to Terraform Cloud/Enterprise, please contact tf-cloud@hashicorp.support.
 If your issue relates to a specific Terraform provider, please open it in the provider's own repository. The index of providers is at https://github.com/terraform-providers.
 
 To fix problems, we need clear reproduction cases - we need to be able to see it happen locally. A reproduction case is ideally something a Terraform Core engineer can git-clone or copy-paste and run immediately, without inventing any details or context.
