-# Sudoku Solver
+# Sudoku Solver v1.0.1
 
-This is a Sudoku solver program written in C++. It allows you to input Sudoku puzzles through the console and solves them using a backtracking algorithm. The program can handle puzzles with empty cells, denoted by '.' or '0', and will output the solved Sudoku grid or notify if the puzzle is invalid (**which means that there is no solution for the sudoku puzzle**). 
+Sudoku Solver v1.0.1 is an enhanced version of the Sudoku solver program written in C++. This update introduces a new library structure, performance improvements, and additional features.
 
-**If there are several solutions for the sudoku, the program will automatically generate one.**
+## Changes in Version 1.0.1
 
-All invalid input chars (not digit nor '.' , neither space) will be considered as empty cells.
+### Library Update
+
+The library has been updated to version 1.0.1 and now includes the following files:
+
+- `SudokuSolver.cpp`: Source file containing the implementation of the SudokuSolver class.
+- `SudokuSolver.h`: Header file declaring the SudokuSolver class.
+- `cmake-build-debug/`: Folder containing build artifacts, including the dynamic link library (`libSudokuServerLib.dll`) and its corresponding import library (`libSudokuServerLib.dll.a`).
+
+Users can choose to use the library as either a static or shared library based on their preferences.
+
+### Improved Performance
+
+In an effort to enhance both time and space efficiency, all unnecessary `int` data types have been changed to `unsigned char`.
 
 ## Files
 
 - `CMakeLists.txt`: CMake configuration file.
-- `main.cpp`: Source code containing the SudokuSolver class and the main program.

 ## Usage
 
 Run the program by executing the `SudokuSolver.exe` file. Enter Sudoku puzzles line by line, with empty cells represented by '.' or '0'. The program will solve the puzzle and display the result. You can enter 'quit' at any time to exit the program.
