+## PHPStan integration
+This library is distributed with PHPStan extension which's providing magic methods reflection. Just add following configuration to your `phpstan.neon`
+```yaml
+services:
+    -
+        class: IW\PHPStan\Reflection\EnumMethodsReflectionExtension
+        tags:
+            - phpstan.broker.methodsClassReflectionExtension

 ## Alternatives

 - PHP's [SplEnum] needs an extension and also does not support singletons.
