+
+A Script to scrape name and price from Jumia Kenya.
+
+## Requirements
+1. Python 3.6 or above
+2. BeautifulSoup
+3. Requests
+4. Json
+
+## Usage
+This script can be used to scrape name and price of any product from Jumia Kenya.
+To use this script, run the following command in your terminal:
+```python index.py```
+The script will prompt you to enter the url of the products you want to scrape.
+Use the url of the main page of the products you want to scrape.
