# Simple Inventory Management System with Zenity
## Project Overview
A user-friendly graphical interface inventory management system will be developed using Zenity tools, supporting operations such as product addition, listing, updating, and deletion. The code must be uploaded publicly to a GITHUB repository. The system's usage should be explained with screenshots in the "Readme.md" file in the GITHUB repository. A 3-4 minute usage video (screen recording with your voice) should be uploaded to Youtube or another video platform and shared in the readme.md. The GITHUB repository link should be uploaded to e-campus.
