+# Music Orchestrator
+
+Search → preview on YouTube → download as tagged MP3, organized for PlexAmp.
+
+## Production deploy (Ubuntu server, local network)
+
+Copy the project to your Ubuntu machine, then:
+
+```bash
+bash deploy.sh
+```
+
+The script installs all dependencies, builds the frontend, configures nginx and
+a systemd service, and starts everything. Re-run it at any time to apply updates.
+
+**Access:** `http://<server-ip>` from any device on your local network.
+
+### After deploy
+
+```bash
+# Stream live logs
+journalctl -u music-orchestrator@<your-user> -f
+
+# Restart the API
+sudo systemctl restart music-orchestrator@<your-user>
+
+# Change music library path
+nano /opt/music-orchestrator/backend/.env
+sudo systemctl restart music-orchestrator@<your-user>
+```
+
+---
+
+## Local development
+
+**Requirements:** Python 3.11+, Node 18+, ffmpeg
+
+```bash
+# Backend
+cd backend
+python -m venv venv
+source venv/bin/activate
+pip install -r requirements.txt
+cp .env.example .env   # set MUSIC_DIR
+uvicorn main:app --reload --port 8000
+```
+
+```bash
+# Frontend (separate terminal)
+cd frontend
+npm install
+npm run dev
+```
+
+Open `http://localhost:5173` — Vite proxies `/api` to the backend automatically.
+
+---
+
+## Music library structure
+
+Downloads are saved as:
+
+```
+Music/
+└── Queen/
+    └── A Night at the Opera/
+        └── 01 - Bohemian Rhapsody.mp3
+```
+
+Set `MUSIC_DIR` in `backend/.env` to your Plex library folder.
+
+## Architecture notes
+
+- **1 uvicorn worker only** — download job state is held in memory. Multiple
+  workers would each have their own job store, breaking status polling.
+- nginx serves the React build as static files and reverse-proxies `/api/*`
+  to the FastAPI backend on `127.0.0.1:8000`.
+- Metadata (title, artist, album, artwork) comes from the iTunes Search API.
+  The YouTube video is only used for audio.

+# React + TypeScript + 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/) (or [oxc](https://oxc.rs) when used in [rolldown-vite](https://vite.dev/guide/rolldown)) 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
+
+## React Compiler
+
+The React Compiler is not enabled on this template because of its impact on dev & build performances. To add it, see [this documentation](https://react.dev/learn/react-compiler/installation).
+
+## Expanding the ESLint configuration
+
+If you are developing a production application, we recommend updating the configuration to enable type-aware lint rules:
+
+```js
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+
+      // Remove tseslint.configs.recommended and replace with this
+      tseslint.configs.recommendedTypeChecked,
+      // Alternatively, use this for stricter rules
+      tseslint.configs.strictTypeChecked,
+      // Optionally, add this for stylistic rules
+      tseslint.configs.stylisticTypeChecked,
+
+      // Other configs...
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
+
+You can also install [eslint-plugin-react-x](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-x) and [eslint-plugin-react-dom](https://github.com/Rel1cx/eslint-react/tree/main/packages/plugins/eslint-plugin-react-dom) for React-specific lint rules:
+
+```js
+// eslint.config.js
+import reactX from 'eslint-plugin-react-x'
+import reactDom from 'eslint-plugin-react-dom'
+
+export default defineConfig([
+  globalIgnores(['dist']),
+  {
+    files: ['**/*.{ts,tsx}'],
+    extends: [
+      // Other configs...
+      // Enable lint rules for React
+      reactX.configs['recommended-typescript'],
+      // Enable lint rules for React DOM
+      reactDom.configs.recommended,
+    ],
+    languageOptions: {
+      parserOptions: {
+        project: ['./tsconfig.node.json', './tsconfig.app.json'],
+        tsconfigRootDir: import.meta.dirname,
+      },
+      // other options...
+    },
+  },
+])
+```
