+# Snake game
+
+Snake game which we used to play in childhood where the snake moves to eat the apple and once it eats, its length increases.
+
+It will be having background music playing as well as a different sound when the snake dies or eats an apple.
+
+It also shows the score of the user in the bottom and also the time elapsed. 
+
+## Setup 
+
+Run the file
+
+`python snake.py`
+
+
+OR 
+
+You can directly open the binary executable file `snake.exe`(for Windows)
