+## Accessibility
+
+`react-native-floating-labels` is designed to work correctly with screen readers (VoiceOver on iOS, TalkBack on Android) and meets WCAG 2.1/2.2 AA, Section 508, and the React Native accessibility model out of the box — with no extra configuration required for common cases.
+
+### Label association (accessibilityLabel)
+
+The component automatically derives `accessibilityLabel` from the `children` string so screen readers announce the label when the input is focused.
+
+```tsx
+// Screen readers announce "Email" when this input receives focus
+<FloatingLabel>Email</FloatingLabel>
+```
+
+Override it by passing `accessibilityLabel` explicitly:
+
+```tsx
+<FloatingLabel accessibilityLabel="Your email address">Email</FloatingLabel>
+```
+
+On web (react-native-web), `accessibilityLabel` is mapped to `aria-label` automatically.
+
+### Disabled state
+
+When `disabled={true}` is passed, the component automatically sets `accessibilityState={{ disabled: true }}` on the input so screen readers announce it as unavailable.
+
+```tsx
+<FloatingLabel disabled>Email</FloatingLabel>
+```
+
+Override or extend `accessibilityState` as needed — your values take precedence:
+
+```tsx
+<FloatingLabel disabled accessibilityState={{disabled: false, selected: true}}>
+  Email
+</FloatingLabel>
+```
+
+### Password fields
+
+When `secureTextEntry={true}` is passed, the component automatically sets:
+
+- `textContentType="password"` (iOS) — enables password autofill and correct VoiceOver announcement
+- `autoComplete="password"` (Android/web) — enables password autofill
+
+```tsx
+<FloatingLabel secureTextEntry>Password</FloatingLabel>
+```
+
+Override when you need a more specific value (e.g. for a new password field):
+
+```tsx
+<FloatingLabel secureTextEntry textContentType="newPassword" autoComplete="new-password">
+  New Password
+</FloatingLabel>
+```
+
+Add an `accessibilityHint` to give users extra context:
+
+```tsx
+<FloatingLabel secureTextEntry accessibilityHint="Must be at least 8 characters">
+  Password
+</FloatingLabel>
+```
+
+### Error messages
+
+Pass `errorMessage` to render error text below the input. It is announced by screen readers whenever the value changes (via `accessibilityLiveRegion="polite"`).
+
+```tsx
+const [error, setError] = React.useState('');
+
+<FloatingLabel value={email} onChangeText={setEmail} errorMessage={error}>
+  Email
+</FloatingLabel>;
+```
+
+### Helper text
+
+Pass `helperText` to render supplementary guidance below the input. Like `errorMessage`, it uses `accessibilityLiveRegion="polite"` for dynamic announcements.
+
+```tsx
+<FloatingLabel helperText="We'll never share your email">Email</FloatingLabel>
+```
+
+### Focus indicators
+
+The component does not enforce focus styles — this keeps it flexible for any design system. To implement a WCAG 2.2-compliant visible focus indicator, use `onFocus`/`onBlur` with `inputStyle`:
+
+```tsx
+const [focused, setFocused] = React.useState(false);
+
+<FloatingLabel
+  inputStyle={focused ? {borderColor: '#0057b8', borderWidth: 2} : undefined}
+  onFocus={() => setFocused(true)}
+  onBlur={() => setFocused(false)}
+>
+  Email
+</FloatingLabel>;
+```
+
+WCAG 2.2 requires the focus indicator to have a contrast ratio of at least 3:1 against adjacent colors.
+
+### Touch target size
+
+Apple and Google both recommend a minimum touch target of **44×44dp**. The component's default height is 40dp. To meet the recommendation, set `style` on the container:
+
+```tsx
+<FloatingLabel style={{minHeight: 44}}>Email</FloatingLabel>
+```
+
+### Screen reader testing checklist
+
+Before shipping, verify the following manually with screen readers enabled:
+
+**iOS — VoiceOver** (`Settings → Accessibility → VoiceOver`):
+
+- [ ] Focusing the input announces the label text
+- [ ] A disabled input is announced as "dimmed" or "unavailable"
+- [ ] A password input is announced as a "secure text field"
+- [ ] Error messages are announced when they appear
+- [ ] Helper text is readable when navigating to the input
+
+**Android — TalkBack** (`Settings → Accessibility → TalkBack`):
+
+- [ ] Focusing the input announces the label text
+- [ ] A disabled input is announced as "disabled"
+- [ ] A password input is announced as a password field
+- [ ] Error messages are announced when they appear
+- [ ] Helper text is readable when navigating to the input
