+"""BRMS - Bank Risk Management Simulation.
+
+BRMS is an educational tool designed to provide users with an in-depth understanding of bank risk management practices.
+It allows users to simulate and respond to various risk scenarios, and analyze the impact on a bank's financial health.
+
+BRMS generally follows the Model-View-Controller (MVC) design pattern for maintainability.
+Additional modules are to implement core functionalities that are independent of the GUI.
