+    Welcome to the Exercise Testing Library!
+
+    This library is designed to help you test your solutions to various exercises.
+
+    How to Use:
+    - Each class in this library corresponds to a specific lesson.
+    - To test your solution, instantiate the class and call the `check_task_task-number` method, passing your function as an argument.
+
+    Example:
+        lesson = Lesson10()
+        print(lesson.check_task_1(my_function))
+
+    Enjoy the process!
