+## Custom Pipeline Code for OIDC Group and Role Mapping
+
+Setting the option `netbox__patch_oidc_group_and_role_mapping_custom_pipeline` to `true` makes this role patch NetBox to add custom pipeline code for OIDC group and role mapping.
+Note that this role uses a patch for NetBox >= 4.0.0.
+The patch is available in `files/0001_oidc_group_and_role_mapping_custom_pipeline.patch`, licensed under the CC BY-SA 4.0 license and taken from [this authentik NetBox documentation](https://docs.goauthentik.io/integrations/services/netbox/).
+The documentation also shows how to use the pipeline code by defining a custom `SOCIAL_AUTH_PIPELINE`, which you also need to do, as the configuration isn't provided by this role.
+See also [the default settings.py](https://github.com/netbox-community/netbox/blob/main/netbox/netbox/settings.py) for the default `SOCIAL_AUTH_PIPELINE`.
