+# Spotify API Setup Instructions
+
+## 🎵 Getting Spotify API Credentials
+
+To enable real Spotify integration in SleepySound, you need to set up a Spotify Developer account and get API credentials.
+
+### Step 1: Create a Spotify Developer Account
+1. Go to [Spotify Developer Dashboard](https://developer.spotify.com/dashboard)
+2. Log in with your Spotify account (create one if needed)
+3. Accept the Terms of Service
+
+### Step 2: Create a New App
+1. Click "Create an App"
+2. Fill in the details:
+   - **App Name**: SleepySound
+   - **App Description**: Collaborative music selection for Lido Schenna
+   - **Redirect URI**: `sleepysound://callback`
+3. Check the boxes to agree to terms
+4. Click "Create"
+
+### Step 3: Get Your Credentials
+1. In your app dashboard, you'll see:
+   - **Client ID** (public)
+   - **Client Secret** (keep this private!)
+2. Copy these values
+
+### Step 4: Configure the App
+1. Open `lib/services/spotify_service.dart`
+2. Replace the placeholder values:
+   ```dart
+   static const String _clientId = 'YOUR_ACTUAL_CLIENT_ID_HERE';
+   static const String _clientSecret = 'YOUR_ACTUAL_CLIENT_SECRET_HERE';
+   ```
+
+### Step 5: Enable Spotify Features
+The app is configured to work with mock data by default. Once you add real credentials:
+- Real Spotify search will be enabled
+- Track metadata will be fetched from Spotify
+- Album artwork will be displayed
+- Preview URLs will be available (if provided by Spotify)
+
+## 🚀 Demo Mode
+The app works without Spotify credentials using demo data. You can:
+- Search for tracks (returns demo results)
+- Vote on songs
+- See the queue update in real-time
+- Experience the full UI/UX
+
+## 🔒 Security Notes
+- Never commit your Client Secret to version control
+- In production, use environment variables or secure storage
+- Consider using Spotify's Authorization Code flow for user-specific features
