+### Basic configuration
+
+```terraform
+data "aws_amp_workspace" "example" {
+  workspace_id = "ws-41det8a1-2c67-6a1a-9381-9b83d3d78ef7"
+}
+```
+
+## Argument Reference
+
+The following arguments are required:

+
+## Attributes Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `arn` - The Amazon Resource Name (ARN) of the Prometheus workspace.
+* `created_date` - The creation date of the Prometheus workspace.
