+# MERN Turborepo Template
+
+A monorepo MERN setup managed by Turborepo.
+
+## Structure
+
+```
+.
+├── package.json          # root with workspaces and turbo scripts
+├── turbo.json            # Turborepo pipeline config
+└── apps
+    ├── client            # React + Vite frontend (App.jsx, assets/react.svg, strict mode)
+    └── server            # Express API backend (server.js, health route)
+```
+
+## Scripts
+
+From the root:
+
+- `npm run dev` – Runs client and server in parallel via Turborepo
+- `npm run build` – Builds all apps
+- `npm run lint` – Lints all workspaces
+- `npm run dev --filter=client` – Run only client
+- `npm run dev --filter=server` – Run only server
+
+## Next Steps After Scaffolding
+
+```
+cd <project-name>
+npm install
+npm run dev
+```
+
+Visit:
+- Client: http://localhost:5173
+- Server: http://localhost:4000/api/health
+
+## Environment Variables
+
+Create a `.env` file in `apps/server/` based on `.env.example`:
+
+```
+PORT=4000
+MONGO_URI=mongodb://localhost:27017/your_db
+NODE_ENV=development
+```
+
+If `MONGO_URI` is omitted, the server will start without a DB connection (scaffold-safe behavior).
+
+## Error Handling
+
+The server includes basic 404 and 500 handlers. Extend these in `server.js` as needed.
+
+## Recommended Next Additions
+
+- Add a shared `packages/` workspace for types/utilities
+- Add Tailwind or UI lib to client
+- Add tests (Vitest + React Testing Library, Supertest for API)
+- Add Dockerfile for deployment
+
+## Customization
+
+Add linting, testing, shared packages, or environment configuration as needed.

+# React + Vite
+
+This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+
+Currently, two official plugins are available:
+
+- [@vitejs/plugin-react](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react) uses [Babel](https://babeljs.io/) for Fast Refresh
+- [@vitejs/plugin-react-swc](https://github.com/vitejs/vite-plugin-react/blob/main/packages/plugin-react-swc) uses [SWC](https://swc.rs/) for Fast Refresh
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend using TypeScript with type-aware lint rules enabled. Check out the [TS template](https://github.com/vitejs/vite/tree/main/packages/create-vite/template-react-ts) for information on how to integrate TypeScript and [`typescript-eslint`](https://typescript-eslint.io) in your project.
