+Configuring Flask Application for Airflow Webserver
+===================================================
+
+``FabAuthManager`` and Airflow 2 plugins uses Flask to render the web UI.When initialized, predefined configuration
+is used, based on the ``webserver`` section of the ``airflow.cfg`` file. You can override these settings
+and add any extra settings by adding flask configuration to ``webserver_config.py`` file specified in ``[fab] config_file`` (by default it is ``$AIRFLOW_HOME/webserver_config.py``). 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_requestq
+    def print_custom_message() -> None:
+        print("Executing before every request")
