-# React + TypeScript + Vite
+# DevUI Frontend
 
-This template provides a minimal setup to get React working in Vite with HMR and some ESLint rules.
+## Build Instructions
 
-Currently, two official plugins are available:
+```bash
+cd frontend
+yarn install
 
-- [@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
+# Create .env.local with backend URL
+echo 'VITE_API_BASE_URL=http://localhost:8000' > .env.local
+
+# Create .env.production (empty for relative URLs)
+echo '' > .env.production
+
+# Development
+yarn dev
+
+# Build (copies to backend)
+yarn build
+```
