+## Updating importer mapping types
+The types returned by the `importer_mappings` endpoint (see [Get Importer Mappings](#get-importer-mappings) below)
+are generated by the `GenerateMappings.py` script here: `staging_service/autodetect/GenerateMappings.py`. 
+Running this script will build the `supported_apps_w_extensions.json` file that should be placed in the
+`deployment/conf` directory.
+
+To add new mappings, update the `GenerateMappings.py` script. New file types and object types should be added
+to the `staging_service.autodetect.Mappings` module and included from there. See `GenerateMappings.py` 
+docstrings for more details.
