 ## Project Overview
 
-This repository is a curated collection of algorithmic implementations in Python, designed to serve as a reference, learning resource, and toolkit for developers and students alike. It spans a wide range of domains, including blockchain, ciphers, data compressions, data structures, linear algebra, etc.

+[TheAlgorithms/Python](https://github.com/TheAlgorithms/Python) is an open-source repository for learning, practicing, and understanding algorithms in Python. It offers a curated collection of algorithm implementations that serve as a reference, educational resource, and practical toolkit for both students and developers. It covers a wide range of domains, including blockchain, cryptography, data compression, data structures, linear algebra, and more.
 
 ## Key Quality Metrics
 
+For the purpose of this assignment, we will be diving into the **[Data Dtructures](https://github.com/SWEN-777/TheAlgorithms-Python/tree/master/data_structures)** directory to evaluate its key quality metrics.
