-Without configuration, PostgREST won't be able to serve requests. At the minimum it needs either :ref:`a role to serve anonymous requests with <db-anon-role>` - or :ref:`a secret to use for JWT authentication <jwt-secret>`. Config parameters can be provided via :ref:`file_config`, via :ref:`env_variables_config` or through :ref:`in_db_config`.

 To connect to a database it uses a `libpq connection string <https://www.postgresql.org/docs/current/libpq-connect.html#LIBPQ-CONNSTRING>`_. The connection string can be set in the configuration file or via environment variable or can be read from an external file. See :ref:`db-uri` for details. Any parameter that is not set in the connection string is read from `libpq environment variables <https://www.postgresql.org/docs/current/libpq-envars.html>`_. The default connection string is ``postgresql://``, which reads **all** parameters from the environment.
