+Vendordata
+==========
+
+Nova supports passing deployer provided data to instances using a
+concept known as Vendordata. If a Vendordata file is located in the
+following path within the Kolla configuration, Kolla will
+automatically use it when the Nova service is deployed or
+reconfigured: ``/etc/kolla/config/nova/vendordata.json``.
