Setup Instructions Prerequisites

Node.js and npm installed on your development machine. A code editor (e.g., VSCode, Sublime Text).

Installation Steps

Clone the repository (if hosted on GitHub or another version control system):Codegit clone cd

Install backend dependencies: Navigate to the backend directory and run:Codenpm install express axios cheerio express-rate-limit cors
