-### How It Works
-
-1. **Launch** the app in MATLAB — the Start screen appears with language selection.
-2. **Select a language**: Korean or English.
-3. **Answer 12 questions** by clicking **A** or **B** (or **Skip** to leave a question blank).
-4. Use the **Back** button to revisit previous answers.
-5. After the last question, the app calculates your **MBTI type** based on 4 dimensions:
-   - **T/F** (Thinking / Feeling): Questions 1, 5, 9
-   - **J/P** (Judging / Perceiving): Questions 2, 6, 10
-   - **E/I** (Extroversion / Introversion): Questions 3, 7, 11
-   - **N/S** (iNtuition / Sensing): Questions 4, 8, 12
-6. The **Result screen** shows your MBTI type, matched engineering role, recommended toolbox, and compatibility.
-7. You can **save your result** as a PNG, **explore the product page**, or **retry** the quiz.

-### Getting Started
-
-```matlab
-% 1. Open MATLAB
-% 2. Navigate to the project directory
-cd /path/to/MBTI
-
-% 3. Run the app
-MBTIApp
-```
-
-Alternatively, open `MBTIApp.m` in **MATLAB App Designer** and click **Run**.
