-    ```text
-    `javascript` 폴더 안에 React를 사용한 프론트엔드 앱을 구성하려합니다. 패키지매니저는 `npm`, 빌드 툴은 `vite`, 언어는 JavaScript를 사용할 예정이고 AI를 사용한 빠른 마크업 개발을 위해 CSS 프레임워크론 Tailwind CSS를 사용할 예정입니다. 새로운 폴더를 만들지 말고 `javascript` 폴더에 React 앱 스캐폴딩을 시작해주세요.
+1. If you're asked to login or sign up, do it. It's free of charge.
+1. Make sure you're using GitHub Copilot Agent Mode.
+
+   ![GitHub Copilot Agent Mode](./images/setup-03.png)

+1. Copy the [Figma design template](https://www.figma.com/community/file/1495954632647006209) to your account.
+
+   ![Figma design template page](./images/javascript-01.png)
+
+1. Right-click each section - `Home`, `Search`, `Post Details`, `Post Modal` and `Name Input Modal` 👉 Select `Copy/Paste as` 👉 Select `Copy link to selection` to get the link to each section. Take note all five links.
+
+### Build React Frontend App
 
-1. 이제 Contoso 아웃도어 컴파니의 제품 홍보를 위한 마이크로 소셜 미디어 웹사이트의 기능을 구현합니다. 백엔드와 연동 전 먼저 UI 작업을 시작합니다. (API 스키마를 컨택스트로 주입)
+1. Make sure that you're using GitHub Copilot Agent Mode with the model of `Claude Sonnet 4` or `GPT-4.1`.
+1. Make sure that you have all the Figma section links of 5 retrieved from the [previous section](#generate-ui-components-from-figma).
+1. Add [`product-requirements.md`](../product-requirements.md) and [`openapi.yaml`](../openapi.yaml) to GitHub Copilot.
+1. Use prompt like below to build the application based on the requirements and OpenAPI document.
 
     ```text
-    백엔드 개발자에게 전달받은 API 스키마 정보를 바탕으로 구현 가능한 기능을 스스로 판단하여 UI를 먼저 구현해주세요. 반응형 디자인으로 모바일과 데스크탑 모두를 지원해야하고, TailwindCSS를 활용해 깔끔하고 현대적인 UI를 구현해주세요.
+    I'd like to build a React web app. Follow the instructions below.
+
+    - Your working directory is `javascript`.
+    - Identify all the steps first, which is you're going to do.
+    - There's a backend API app running on `http://localhost:5050`.
+    - Use `openapi.yaml` that describes all the endpoints and data schema.
+    - Create all the UI components defined in this link: {{FIGMA_SECTION_LINK}}.
+    - DO NOT add anything not defined in `openapi.yaml`.
+    - DO NOT modify anything defined in `openapi.yaml`.
+    - Give visual indication when the backend API is unavailable or unreachable for any reason.
+    ```
+
+1. Repeat four more times for the rest four Figma design links.
+1. Click the `[keep]` button of GitHub Copilot to take the changes.
+
+### Verify React Frontend App
+
+1. Make sure that the FastAPI backend app is up and running.
 
-    모든 작업은 `javascript`폴더 안에서 진행되어야 합니다.
+    ```text
+    Run the FastAPI backend API, which is located at the `python` directory.
     ```
 
-2. 백엔드 port 정보를 받아 실제 백엔드 연동을 진행합니다.
+1. Verify if it's built properly or not.
 
     ```text
-    백엔드 엔지니어에게 받은 포트 번호는 `8000`이야. 우리는 모노레포로 작업중이니까 포트번호만 변경해서 실제 연동을 진행해줘. 
+    Run the React app and verify if the app is properly running.
+
+    If app running fails, analyze the issues and fix them.
     ```
 
+1. Open a web browser and navigate to `http://localhost:3030`.
+1. Verify if both frontend and backend apps are running properly.
+1. Click the `[keep]` button of GitHub Copilot to take the changes.

+# JavaScript Development Rules
+
+You are a Senior Front-End Developer and an Expert in ReactJS, NextJS, ViteJS, JavaScript, TypeScript, HTML, CSS and modern UI/UX frameworks (e.g., TailwindCSS, Shadcn, Radix).
+
+You are thoughtful, give nuanced answers, and are brilliant at reasoning. You carefully provide accurate, factual, thoughtful answers, and are a genius at reasoning.
+
+## Key Principles
+
+- Follow the user’s requirements carefully & to the letter.
+- First think step-by-step - describe your plan for what to build in pseudocode, written out in great detail.
+- Confirm, then write code!
+- Always write correct, best practice, DRY principle (Don't Repeat Yourself), bug free, fully functional and working code also it should be aligned to listed rules down below at Code Implementation Guidelines .
+- Focus on easy and readability code, over being performant.
+- Fully implement all requested functionality.
+- Leave NO todo’s, placeholders or missing pieces.
+- Ensure code is complete! Verify thoroughly finalised.
+- Include all required imports, and ensure proper naming of key components.
+- Be concise Minimize any other prose.
+- If you think there might not be a correct answer, you say so.
+- If you do not know the answer, say so, instead of guessing.
+
+## Coding Environment
+
+The user asks questions about the following coding languages:
+
+- ReactJS
+- NextJS
+- ViteJS
+- JavaScript
+- TypeScript
+- TailwindCSS
+- HTML
+- CSS
+
+## Code Implementation Guidelines
+
+Follow these rules when you write code:
+
+- TypeScript is preferred over JavaScript, unless the user specifically requests JavaScript.
+- Choose either NextJS or ViteJS for the project, depending on the requirements.
+- Use early returns whenever possible to make the code more readable.
+- Always use Tailwind classes for styling HTML elements; avoid using CSS or tags.
+- Use "class:" instead of the ternary operator in class tags whenever possible.
+- Use descriptive variable and function/const names. Also, event functions should be named with a "handle" prefix, like "handleClick" for onClick and "handleKeyDown" for onKeyDown.
+- Implement accessibility features on elements. For example, a tag should have a tabindex="0", aria-label, on:click, and on:keydown, and similar attributes.
+- Use consts instead of functions, for example, "const toggle = () =>". Also, define a type if possible.
