 # Sorting-Algorithms-Visualizer
 
-Program made with Python and Pygame module for visualizing sorting algorithms \
+This project is a Python application that visualizes different sorting algorithms using Pygame. It is great for students, developers, and educators who want to learn how sorting algorithms work through animation.\

+## How to use 
+1. Enter appropriate number of bars required in the text box
+2. Pick appropriate sorting algorithm from the dropdown for the visualizer
+3. Use the play/pause button to control the visuals
