-To automatically attach code references to the asset's function definition, you can use the `dagster._core.definitions.metadata.with_source_code_references` utility. Any asset definitions passed to the utility will have their source file attached as metadata.

 Dagster also supports fetching additional metadata at dbt execution time to attach to asset materializations. For more information, see the [Customizing asset materialization metadata](#customizing-asset-materialization-metadata) section.
 
+#### Attaching code reference metadata
+
+Dagster's dbt integration can automatically attach [code reference](/guides/dagster/code-references) metadata to the SQL files backing your dbt assets. To enable this feature, set the `enable_code_references` parameter to `True` in the <PyObject module="dagster_dbt" object="DagsterDbtTranslatorSettings" /> passed to your <PyObject module="dagster_dbt" object="DagsterDbtTranslator" />:
