Quick Start with Setup Script

The easiest way to run the entire application is using our setup script:

1. Make the script executable:

   chmod +x setup.sh
   

2. Run the setup script:

   ./setup.sh
   

3. Follow the prompts:

   • The script will create necessary .env files if they don't exist
   • Choose between Docker Compose deployment or local development
   • The script will guide you through the rest of the setup process

For Windows users, use setup.bat instead.

Quick Start with Docker Compose Manually

If you prefer to run the commands manually:

1. Set up environment variables:

   # For backend
   cp backend/.env.example backend/.env
   # Edit the .env file to add your OpenAI API key
   
   # For frontend
   cp frontend/.env.example frontend/.env
   

2. Start the application:

   docker-compose up -d
   

3. Access the application:

   • Frontend: http://localhost:3000
   • Backend API: http://localhost:8080
   • API documentation: http://localhost:8080/docs

4. Stop the application:

   docker-compose down
