+QUICK START
+================================================================================
+
+1. Verify Implementation:
+   python3 test_wav_feature.py
+
+2. Test with Real API (requires API key):
+   export SUNO_API_KEY="your-key-here"
+   python3 test_wav_integration.py
+
+3. Usage Example:
+   from suno_client import SunoClient
+   client = SunoClient()
+   
+   # Generate music
+   music = await client.generate_music(prompt="Epic soundtrack", wait_audio=True)
+   track_id = music['data'][0]['id']
+   
+   # Convert to WAV
+   conversion = await client.convert_to_wav(track_id, "https://example.com/webhook")
+   task_id = conversion['data']['taskId']
+   
+   # Check status
+   status = await client.get_wav_conversion_status(task_id)
+
