# Requirements Document
|
|
|
|
## Introduction
|
|
|
|
This document outlines the requirements for building a Terminal User Interface (TUI) for the Shopify Price Updater script. The TUI will provide an interactive, menu-driven interface that allows users to configure settings, execute operations, schedule price updates, and monitor progress without needing to use command-line arguments or edit environment files directly. The interface will make the tool more accessible to non-technical users while maintaining all existing functionality.
