vicerhatech/mern-training ? reverse-engineered prompt

Build me a simple MERN practice app in this repo, something clean and easy to run locally.

I want a small full stack app with a basic home page, a way to add, view, edit, and delete a few records, and a simple API behind it so I can practice the flow from browser to server to database. Keep the UI plain but polished enough to use, with clear forms, a list view, and helpful messages when something goes wrong.

Set it up so I can start it easily, and make sure the code is organized in a way that is easy to learn from and extend later. If you need to check the current docs for anything, go ahead and look them up online. Also leave a short README update that explains how to run it and what the main pieces do.
