+
+## Design Philosophy
+
+### Glassmorphism
+All modals use a glassmorphism design with:
+- Frosted glass blur effect
+- Semi-transparent backgrounds
+- Subtle borders and shadows
+- Smooth animations
+
+### Accessibility
+- ARIA labels on all interactive elements
+- Keyboard navigation support
+- Focus management in modals
+- Screen reader announcements
+- High contrast mode support
+- Reduced motion support for users who prefer it
+
+### Responsive Design
+- Mobile-first approach
+- Touch-friendly on mobile devices
+- Adaptive layouts for different screen sizes
+- Graceful degradation on older browsers
+
+### Performance
+- CSS animations preferred over JavaScript
+- Minimal DOM manipulation
+- No external dependencies
+- Lazy initialization
+
+## Browser Support
+- Chrome 90+
+- Firefox 88+
+- Safari 14+
+- Edge 90+
+
+## Integration Examples
+
+### Show toast on successful form submission
+```javascript
+document.querySelector('form').addEventListener('submit', async (e) => {
+  e.preventDefault();
+
+  try {
+    await submitForm();
+    window.toastSystem.showToast({
+      type: 'success',
+      title: 'Form Submitted',
+      message: 'Your data has been saved successfully'
+    });
+  } catch (error) {
+    window.toastSystem.showToast({
+      type: 'error',
+      title: 'Submission Failed',
+      message: error.message
+    });
+  }
+});
+```
+
+### Show skeleton while loading data
+```html
+<!-- Initially show skeleton -->
+<div id="data-container" class="skeleton-grid">
+  <div class="skeleton-card">...</div>
+  <div class="skeleton-card">...</div>
+</div>
+
+<script>
+async function loadData() {
+  const container = document.getElementById('data-container');
+
+  // Data loads...
+  const data = await fetchData();
+
+  // Replace skeleton with actual content
+  container.innerHTML = renderData(data);
+}
+</script>
+```
+
+### Custom command in command palette
+```javascript
+// Add a custom command to the palette
+window.commandPalette.commands.push({
+  id: 'custom-action',
+  name: 'My Custom Action',
+  icon: '⚡',
+  category: 'Custom',
+  action: () => {
+    console.log('Custom action executed');
+    window.toastSystem.showToast({
+      type: 'success',
+      title: 'Custom Action',
+      message: 'Action completed'
+    });
+  },
+  keywords: ['custom', 'action', 'my']
+});
+```
+
+## Theme Support
+All features support both dark and light themes:
+- Dark theme (default)
+- Light theme (toggle with `Alt+T` or theme button)
+
+Themes are persisted in `localStorage` and apply automatically on page load.
+
+## Future Enhancements
+Potential future improvements:
+- Command palette command history
+- Toast notification queue management
+- More skeleton component variants
+- Customizable keyboard shortcuts
+- Command palette plugins/extensions
+- Toast notification templates
