-# Sudoku
+# Sudoku Generator

-## Sudoku solver
-NOTE: not all puzzles in source are valid!
+This project is just a collection of research regarding the generation of sudoku's.
+It's not a production project.

-## Sudoku generator
+The main focus is on the generation of sudoku's using several algorithms like backtracking. 
+
+## Applications
+
+### Sudoku Generator
+Just execute application and it will generate a sudoku for you with certain complexity.
+
+### Sudoku Solvder
+Give sudoku puzzle as input and it will solve it for you
+
+### Sudoku Web
+Run this server and it will run multiple sudoku generators and keeps track of many statistics while generating them. 
+
+### Screenshots
+Will come when I figured out how to use this project again.
+
+## How to use 
+
+I don't know. I have to figure out. It is a while ago that I wrote this.
