```

## Usage Examples

### Quick Start
1. Open `index.html` in a modern browser
2. Click "ENTER THE GRID" to initialize
3. Use keyboard shortcuts or terminal for control
4. Press 'E' to cycle through visual effects

### Terminal Usage
```bash
# Open terminal
Press 'T'

# Switch to a specific effect
effect tron

# Adjust volume
volume 7

# Check what's playing
status

# Get help
help
```

## Development Notes

### Adding New Effects
1. Create new effect function following the pattern:
```javascript
const newEffect = () => {
  setTimeout(() => {
    // Hydra effect code here
    .out();
  }, 100);
};
```

2. Add to `hydraEffects` array
3. Update terminal command switch statement
4. Add to help text

### Hydra Syntax Tips
- Use `scrollX()` and `scrollY()` for positioning (not `translate()`)
- Use `shape(32, ...)` for smooth circles (not `shape(4, ...)`)
- Always end effect chains with `.out()`
- Use `setTimeout()` wrapper for stability

## Troubleshooting

### Common Issues
1. **Effects not loading**: Check browser WebGL support
2. **Audio not playing**: Check CORS and network connectivity
3. **Mobile controls not working**: Ensure touch events are enabled
4. **Terminal not responding**: Check for JavaScript errors in console

### Browser Requirements
- WebGL support for Hydra effects
- Modern ES6+ JavaScript support
- Audio API support for music playback
- Local storage for playlist history
