+The **client** directory contains codes and configurations/settings for the (React) NextJS v13 + Material UI v5 front end and Firebase. The folder tree displays the relevant files and folders.
 
 The NextJS frontend uses the [**pages router**](https://nextjs.org/docs/pages) since this is suitable for generating static pages to host on GitHub Pages. It uses the `"container component"` as a dominant pattern, also known as `"component and presentational"` components, for distinguishing between logic (container) and UI (component).
