Summary

Restructured the README.md to improve document organization and add QR code access information for the MBTI quiz application.

Key Changes

• Added QR code section at the top of the README with visual reference and bilingual instructions for quick app access
• Reordered documentation structure: Moved English version content to the end of the document, with Korean version now appearing first
• Updated project structure documentation: Added reference to qrcode.png in the images directory for both Korean and English sections
• Maintained all existing content: No information was removed, only reorganized for better user experience and accessibility

Notable Details

• The QR code section is prominently placed at the beginning with centered alignment and bilingual text ("QR 코드를 스캔하여 바로 접속하세요 / Scan to open the app")
• Both language versions now include the qrcode.png reference in their respective project structure sections
• The document now prioritizes Korean content first, followed by English, reflecting potential user base preferences
