We've automated everything for you. Get up and running in **seconds**.

### 1️⃣ Prerequisite Check
Ensure you have these installed:
- [**Python 3.10+**](https://www.python.org/downloads/) (⚠️ **Crucial:** Check **"Add Python to PATH"** during install)
- [**Node.js 18+**](https://nodejs.org/)
- **FFmpeg** (See the [Setup Guide](#-ffmpeg-setup-critical) below)

### 2️⃣ One-Click Setup
Double-click the **`setup_windows.bat`** file in the root directory.
> ☕ Grab a coffee while it installs backend and frontend dependencies automatically.

### 3️⃣ Launch
Double-click the **`run_app.bat`** file.
> 🌐 The app will automatically open in your browser at `http://localhost:3000`.

---

## 💻 Manual Installation (Dev)

Prefer the command line? Here is how to set it up manually.

### Backend Setup
```bash
cd backend
python -m venv venv
# Activate venv:
# Windows: venv\Scripts\activate
# Mac/Linux: source venv/bin/activate

pip install -r requirements.txt
uvicorn app.main:app --reload --host 0.0.0.0 --port 8000
```

### Frontend Setup
Open a new terminal:
```bash
cd frontend
npm install
npm run dev
# App runs at http://localhost:3000
```

---

## ⚠️ FFmpeg Setup (Critical)

**Vortex needs FFmpeg** to merge high-quality video and audio streams (e.g., 1080p+ usually separates audio/video). Without specific FFmpeg setup, downloads may fail or have no sound.

> [!IMPORTANT]
> **Windows Users:**
> 1. Download `ffmpeg-git-full.7z` from [gyan.dev](https://www.gyan.dev/ffmpeg/builds/).
> 2. Extract and rename the folder to `ffmpeg`.
> 3. Move it to `C:\ffmpeg`.
> 4. **Add to Path**: Search "Edit the system environment variables" -> Environment Variables -> System variables -> Path -> Edit -> New -> Add `C:\ffmpeg\bin`.
> 5. **Restart your PC** or Terminal to apply changes.

Verify installation by running:
```bash
ffmpeg -version
```

---

## 📱 Mobile Access (Local Wi-Fi)

Want to download directly to your phone?

1. Ensure your PC and Phone are on the **same Wi-Fi**.
2. Open Command Prompt (`Win+R` -> `cmd`) and type `ipconfig`.
3. Note your **IPv4 Address** (e.g., `192.168.1.5`).
4. On your phone browser, go to: `http://192.168.1.5:3000`

---

## 🔧 Troubleshooting
