Prerequisites

• Python 3.7+
• Node.js and npm
• Git (optional)

---

Backend Setup (FastAPI)

1. Navigate to the backend directory:

   cd backend

2. (Optional) Create and activate a virtual environment:

   python -m venv venv
   # On Windows:
   venv\Scripts\activate
   # On macOS/Linux:
   source venv/bin/activate

3. Install dependencies:

   pip install fastapi uvicorn python-multipart

4. Run Backend Server:

   uvicorn main:app --reload

Frontend Setup (React)

1. Navigate to the frontend directory:

   cd frontend

2. Install dependencies:

   npm install

3. Run frontend development Server:

   npm start

Usage:

• Open the frontend in your browser.
• Upload two text files using the upload buttons.
• Click Start Scanning.
• The similarity percentage and matched lines will display.

Notes

• Make sure the backend server is running before using the frontend.
• The backend supports CORS, so frontend and backend can run on different ports locally.
