+# FoodSnap AI - Simple Calorie Estimator CLI
+
+---
+
+## 🚀 Project Overview
+
+**FoodSnap AI** is a lightweight Python command-line tool designed to estimate the caloric content and macronutrient breakdown (protein, carbs, fats) of a food item based on user input. It leverages a food nutrition API (such as Spoonacular) to provide accurate nutritional data quickly and easily — no manual lookup required!
+
+---
+
+## ✨ Features
+
+- Accepts **food item name** as input via CLI.
+- Retrieves **calories, protein, carbohydrates, and fat** estimates from an API.
+- Minimalistic command-line interface — easy and fast to use.
+- Built using Python and the popular `requests` library for HTTP requests.
+
+---
+
+## 🛠️ Tech Stack
+
+- **Python 3.x**
+- **requests** library
+- **Spoonacular API** (or any equivalent food nutrition API)
