+If you cannot hard-code your database or schema, you can provide the names of environment variables that contain these values:
+
+```yml
+vars:
+    zendesk_database_env_var: your_destination_name
+    zendesk_schema_env_var: your_schema_name

 This package takes into consideration that not every Zendesk account utilizes the `schedule`, `domain_name`, `user_tag`, `organization_tag`, or `ticket_form_history` features, and allows you to disable the corresponding functionality.
