+# Day02 – Number Guessing Game 
+
+Hi! This is my second day contribution to the 30 Days – 30 Python Projects challenge. I'm building a simple number guessing game using Python to sharpen my logic and input/output skills.
+
+## 📝 Project Description
+This Python script generates a random number between 1 and 100. The user is prompted to guess the number, and the program provides feedback — whether the guess is too high, too low, or correct. It also tracks the number of attempts.
+
+## 🚀 How to Run
+Make sure Python is installed, then run the script using ;)
