-Configuring Flask Application for Airflow Webserver
-===================================================
-
-Airflow uses Flask to render the web UI. When you initialize the Airflow webserver, predefined configuration
-is used, based on the ``webserver`` section of the ``airflow.cfg`` file. You can override these settings
-and add any extra settings however by adding flask configuration to ``webserver_config.py`` file in your
-``$AIRFLOW_HOME`` directory. This file is automatically loaded by the webserver.
-
-For example if you would like to change rate limit strategy to "moving window", you can set the
-``RATELIMIT_STRATEGY`` to ``moving-window``.
-
-You could also enhance / modify the underlying flask app directly,
-as the `app context <https://flask.palletsprojects.com/en/2.3.x/appcontext/>`_ is pushed to ``webserver_config.py``:
-
-.. code-block:: python
-
-    from flask import current_app as app
-
-
-    @app.before_request
-    def print_custom_message() -> None:
-        print("Executing before every request")
