 ## Project Overview
 
-The TI Minor Grade Generator is a distributed ROS2-based system designed to manage student exam results and calculate final course grades. The system follows microservices architecture principles with clear separation of concerns and robust data management.
+Giving marks to students cost a lot of time and pain. For this a automatic solution is needed.
+Therefore the overall Software architect (Tilmann K.) has designed a solution for the ROS2 architecture.

 ## Unit Tests
 
 Unit tests for `DatabaseManager` are implemented in `src/g2_2025_grade_calculator_pkg/test/DatabaseManager.test.cpp` using Google Test and ROS2 test utilities. The tests are designed to work reliably whether a database connection is available or not, focusing on error handling and method behavior validation.
