+## Import (Beta)
+
+Use the [`import` block](https://developer.hashicorp.com/terraform/language/import) to add source configs created directly in Data Control Tower into a Terraform state file. 
+
+For example:
+```terraform
+import { 
+    to = delphix_database_postgresql.source_config_import
+    id = "source_config_id"
+}
+```
+
+*This is a beta feature. Delphix offers no guarantees of support or compatibility.*
