+## React Compatibility
+
+This library supports React 16.8+ (with Hooks), React 17, React 18, and React 19.
+
+**Supported versions:**
+- React 16.8.0 or higher
+- React 17.x
+- React 18.x
+- React 19.x
+
+**Note:** CI currently tests against React 18.x. While the library is compatible with React 16.8+, 17.x, and 19.x based on the peer dependency declaration, full automated test coverage across all versions is not yet implemented.

 ## Usage
 
 The way you specify rules and error messages in HTML5 is by giving first a rule prop, e.g. `required`, `min`, `maxLength`, and then an error message prop, e.g. `valueMissing`, `rangeUnderflow`, or `tooLong`, respectively. This library comes with built-in English defaults for the error messages, but you will probably want to override those by passing in your own.
