## Overview

ShoppingList is a browser-based shopping-list website. Users can start from the home page and open the list manager to add items individually or in bulk, edit and reorder them, and import, export, or merge JSON lists. The manager owns list state and coordinates the table, modal, and list utilities. The shared app shell supplies navigation and the About modal. The README is minimal; additional capabilities are documented in the home and About components. No persistent storage implementation is established by the excerpts.

Main entry points: [`src/pages/ShoppingListPage.jsx`](https://github.com/romanbr87/shoppinglist/blob/main/src/pages/ShoppingListPage.jsx) (List manager), [`src/components/ShoppingListTable.jsx`](https://github.com/romanbr87/shoppinglist/blob/main/src/components/ShoppingListTable.jsx) (Shopping list table), [`src/pages/_app.js`](https://github.com/romanbr87/shoppinglist/blob/main/src/pages/_app.js) (App shell), [`src/pages/index.jsx`](https://github.com/romanbr87/shoppinglist/blob/main/src/pages/index.jsx) (Home page)
