## Overview

ATT is a small Windows software updater. The user starts `main()`, which checks the operating system, displays a temporary Tkinter notification, and runs Winget’s silent upgrade command; failures trigger an error notification. The sole source file implements both orchestration and notification animation. The README describes the same workflow; no separate storage or update-management layer is present.

Main entry points: [`main.py`](https://github.com/fernandoaab/att/blob/main/main.py) (Updater entry point)
