+ *
+ * If this button doesn't look right for your app, you can build your own
+ * button using [TouchableOpacity](docs/touchableopacity.html)
+ * or [TouchableNativeFeedback](docs/touchablenativefeedback.html).
+ * For inspiration, look at the [source code for this button component](https://github.com/facebook/react-native/blob/master/Libraries/Components/Button.js).
+ * Or, take a look at the [wide variety of button components built by the community](https://js.coach/react-native?search=button).
+ *
+ * Example usage:
+ *
+ * ```
+ * import { Button } from 'react-native';
+ * ...
+ *
+ * <Button
+ *   onPress={onPressLearnMore}
+ *   title="Learn More"
+ *   color="#841584"
+ *   accessibilityLabel="Learn more about this purple button"
+ * />
