-# The Ultimate Python Course
+## Python Learning & Practice Repository
 
-Welcome to [**The Ultimate Python Course!**](https://youtu.be/UrsmFxEIp5k)
+This repository is forked from CodeWithHarry's Python course.
+I use it to learn Python by rewriting examples,
+adding my own practice, notes, and small improvements.
 
-This course is designed to take you from a  beginner to an advanced Python programmer. The repository contains all the source code, projects, problem sets, and additional resources to supplement your learning.
-This is a part of my video The Ultimate Python Couse. Refer to this [video](https://youtu.be/UrsmFxEIp5k) to watch my Python course
+### What I am doing here
+- Rewriting course code in my own way
+- Adding comments and explanations
+- Creating small practice programs
+- Learning Git and GitHub workflow
