+# Simple Weather App 
+
+## Project Overview 
+- **Purpose:** This is a simple weather app created to foster the understanding of the fundamentals of Weather API.
+- **Tools Used:** Python, requests library, OpenWeatherMap API.
+- **API Used:** OpenWeatherMap’s Current Weather Data API.
+
+## Setup Instructions
+1. Installing Requirements
+```bash
+pip install requests
+```
+2. Obtain an API Key:
+Sign up at [OpenWeatherMap](https://openweathermap.org/api) to get your free API key.
+
+Project Structure
+```bash
+├── main.py
+├── readme.md
+├── requirements.txt
+└── test_main.py
+```
+
+## Running the app
+```bash
+python main.py
+```
+
+## Running tests
+```bash
+pytest
+```
