-In the project directory, you can run:
+문항은 객관식, 주관식, 서술형으로 구성됩니다.
 
-### `npm start`
+**서술형 문제의 경우**, 직접 답변을 작성하면 AI 해설도 함께 받아보실 수 있어요!!
+> 이 서비스는 수익 창출을 목적으로 하지 않으며, 많은 분께 도움이 되길 바라는 마음으로 운영됩니다!
 
-Runs the app in the development mode.\
-Open [http://localhost:3000](http://localhost:3000) to view it in the browser.

-Launches the test runner in the interactive watch mode.\
-See the section about [running tests](https://facebook.github.io/create-react-app/docs/running-tests) for more information.
 
-### `npm run build`
+## 기술 스택
 
-Builds the app for production to the `build` folder.\
-It correctly bundles React in production mode and optimizes the build for the best performance.
+### **Frontend With `ClaudeCode🚀`**
+- **React, TypeScript, Vite, Tailwind CSS**
 
-The build is minified and the filenames include the hashes.\
-Your app is ready to be deployed!
+### **State Management**
+- **React Query** - 서버 상태 관리
+- **React Router** - 클라이언트 사이드 라우팅
+- **Custom Hooks** - 재사용 가능한 로직 분리
 
-See the section about [deployment](https://facebook.github.io/create-react-app/docs/deployment) for more information.
+### **Authentication**
+- **HttpOnly Cookies** - 보안성 강화된 토큰 관리
+- **Automatic Token Refresh** - 무중단 인증 유지
+- **Social Login Integration** - 간편한 소셜 로그인
 
-### `npm run eject`
+### **Development Tools**
+- **ESLint + Prettier** - 코드 품질 관리
+- **Docker** - 컨테이너화된 개발 환경
+- **GitHub Actions** - 자동화된 CI/CD
 
-**Note: this is a one-way operation. Once you `eject`, you can’t go back!**
+## 시작하기
 
-If you aren’t satisfied with the build tool and configuration choices, you can `eject` at any time. This command will remove the single build dependency from your project.
+### **Prerequisites**
+- Node.js 18.0 이상
+- npm 또는 yarn
+- Docker (선택사항)
 
-Instead, it will copy all the configuration files and the transitive dependencies (webpack, Babel, ESLint, etc) right into your project so you have full control over them. All of the commands except `eject` will still work, but they will point to the copied scripts so you can tweak them. At this point you’re on your own.
+### **설치 및 실행**
 
-You don’t have to ever use `eject`. The curated feature set is suitable for small and middle deployments, and you shouldn’t feel obligated to use this feature. However we understand that this tool wouldn’t be useful if you couldn’t customize it when you are ready for it.
+```bash
+# 저장소 클론
