 # Provisioners Without a Resource
 
 If you need to run provisioners that aren't directly associated with a specific
-resource, you can associate them with a `null_resource`.
+resource, you can associate them with a `terraform_data`.
 
 Instances of [`terraform_data`](/terraform/language/resources/terraform-data) are treated
 like normal resources, but they don't do anything. Like with any other resource
 type, you can configure [provisioners](/terraform/language/resources/provisioners/syntax)
 and [connection details](/terraform/language/resources/provisioners/connection) on a
-`terraform_data` resource. You can also use its `triggers` argument and any
+`terraform_data` resource. You can also use its `input` argument, `triggers_replace` argument, and any
 meta-arguments to control exactly where in the dependency graph its
 provisioners will run.
