 # Provider Documentation
 
-Every Terraform provider has its own documentation, describing its resource
-types and their arguments.
-
-The [Terraform Registry](https://registry.terraform.io/browse/providers) is the
-main home for provider documentation. When viewing a provider's page on the
-Terraform Registry, you can click the "Documentation" link in the header to
-browse its documentation.
-
-Provider documentation in the Registry is versioned; you can use the version
-menu in the header to change which version you're viewing.
