 ## Configuration
+### Middleware
+`WAPI_NETVS_SUPERUSER` is the superuser for the middleware.
+When queries are required which are not possible as the requesting user (due to permission restrictions), the superuser is used.
+Therefore, the user must have the necessary permissions to execute those queries.
+Typically, a user with `cntl.default_reader` and `wapi.devel_tester` is used.
+
+As the queries are executed directly against the database, no token for the user is required; it will only be used to populate the context of the query.
