+# MultiSelect Accessibility Guide
+
+This MultiSelect component provides full keyboard accessibility and screen reader support following WCAG 2.1 AA guidelines.
+
+## Keyboard Navigation
+
+- **Tab** - Focus the trigger button
+- **Enter/Space** - Open/close dropdown when focused
+- **Arrow Up/Down** - Navigate through options when dropdown is open
+- **Enter/Space** - Select/deselect options when navigating
+- **Escape** - Close dropdown
+
+## Screen Reader Support
+
+- Uses \`role="combobox"\` to identify as dropdown
+- \`aria-haspopup="listbox"\` indicates popup contains list
+- \`aria-expanded\` shows dropdown state
+- \`aria-label\` provides accessible name with i18n fallback
+- Selected count announced to screen readers
+
+## Testing Instructions
+
+1. **Tab Navigation**: Use Tab key to focus the component
+2. **Keyboard Opening**: Press Enter or Space to open dropdown
+3. **Option Navigation**: Use Arrow keys to navigate options
+4. **Selection**: Press Enter/Space to select options
+5. **Closing**: Press Escape to close dropdown
+6. **Screen Reader**: Test with screen reader software
+
+Try these stories with keyboard-only navigation!
