+## 라이브러리 운영 방향
+
+**react-simplikit은 이제 완전히 순수한 상태/로직 훅만을 위한 Universal Hook Library로 유지됩니다.**
+
+react-simplikit은 웹/앱(React Native 등) 어디서든 동작 가능한, **플랫폼에 종속되지 않은 순수 상태/로직 훅만을 제공하는 라이브러리**로 재편됩니다.
+
+### 유지되는 것: 순수 상태/로직 훅
+
+특정 플랫폼 API에 의존하지 않는 순수 로직 기반 훅들은 계속 제공돼요:
+
+- `useToggle`, `useBooleanState`, `useCounter` 같은 상태 관리 훅
+- `usePrevious`, `useMount` 같은 라이프사이클 훅
+- `useDebounce`, `useThrottle` 같은 유틸리티 훅
+- **기존 프로젝트의 Backward Compatibility(BC)는 보존돼요**
+
+### Deprecated 되는 것: 브라우저/플랫폼 결합 훅
+
+다음과 같이 브라우저에 강하게 의존하는 훅들은 Deprecated 처리돼요:
+
+- `useGeolocation` - `navigator.geolocation` 의존
+- `useStorageState` - `localStorage`/`sessionStorage` 의존
+- `useIntersectionObserver` - `IntersectionObserver` API 의존
+- `useImpressionRef` - `IntersectionObserver` + Visibility API 의존
+- `useDoubleClick`, `useLongPress` - DOM 이벤트 + `window.setTimeout` 의존
+- `useOutsideClickEffect` - DOM 이벤트 + `document` 의존
+- `useVisibilityEvent` - `document.visibilityState` 의존
+
+이 훅들은:
+
+- 새 기능 추가나 적극적인 고도화는 진행하지 않고
+- 문서 상에서 `@deprecated`로 명시하고
+- 장기적으로는 메이저 버전 업데이트에서 제거를 검토할 수 있어요
+
+### 패키지 상태
+
+- react-simplikit은 **아카이브하지 않아요**
+- 순수 상태/로직 훅들은 계속 유지돼요
+- 치명적인 버그 수정, 최소한의 유지보수는 계속 진행할 예정이에요
+- 새로운 브라우저/플랫폼 종속 훅을 추가하는 일은 이제 지양해요

+## Library Direction
+
+**react-simplikit is now maintained as a Universal Hook Library providing only pure state/logic hooks.**
+
+We are repositioning react-simplikit to focus exclusively on **platform-independent hooks** that work seamlessly across web and mobile (React Native, etc.).
+
+### What's Maintained: Pure State/Logic Hooks
+
+Hooks that don't depend on specific platform APIs will continue to be actively maintained:
+
+- State management hooks like `useToggle`, `useBooleanState`, `useCounter`
+- Lifecycle hooks like `usePrevious`, `useMount`
+- Utility hooks like `useDebounce`, `useThrottle`
+- **Backward compatibility (BC) is preserved** for these existing pure logic hooks
+
+### What's Deprecated: Browser/Platform-Dependent Hooks
+
+The following hooks that strongly depend on browser-specific APIs are now deprecated:
+
+- `useGeolocation` - depends on `navigator.geolocation`
+- `useStorageState` - depends on `localStorage`/`sessionStorage`
+- `useIntersectionObserver` - depends on `IntersectionObserver` API
+- `useImpressionRef` - depends on `IntersectionObserver` + Visibility API
+- `useDoubleClick`, `useLongPress` - depend on DOM events + `window.setTimeout`
+- `useOutsideClickEffect` - depends on DOM events + `document`
+- `useVisibilityEvent` - depends on `document.visibilityState`
+
+These hooks:
+
+- Will not receive new features or major enhancements
+- Are marked as `@deprecated` in documentation
+- May be removed in future major versions
+
+### Package Status
+
+- react-simplikit will **not be archived**
+- Pure state/logic hooks will continue to be maintained
+- Critical bug fixes and minimal maintenance will continue
+- No new browser/platform-dependent hooks will be added
+

 `react-simplikit`은 React 환경에서 유용하게 사용할 수 있는 다양한 도구들을 제공하는 가볍고 강력한 라이브러리예요. React의 설계 원칙을 존중하면서 동시에, React의 개발 경험을 개선하기 위해 설계되었어요.
