Install dependencies: `npm install` 2. Start MongoDB locally or use MongoDB Atlas 3. Run the server: `npm start` 4. Open the frontend in your browser The prototype simulates the core functionality with mock data while maintaining a production-ready architecture that can easily be connected to real APIs (Twitter API, Reddit API, LinkedIn API) and AI services (OpenAI for content generation) when you're ready to scale.
