-`logging <https://docs.python.org/3/howto/logging.html>`_ is Python's builtin standard logging library and can be integrated with `LoggingConfig` as the `root` logging. By using `logging_config()()` you can build a `logger` to be used around your project.
+The ``LoggingConfig.configure()`` method returns a reference to ``logging.getLogger`` which can be used to access a
+logger instance. Thus, the root logger can retrieved with ``logging_config.configure()()`` as shown in the example
