${BOLD}Next Steps:${RESET}

  1. Edit ${CYAN}.env${RESET} with your:
     - RPC_URL (Alchemy/Infura/etc)
     - PRIVATE_KEYS (comma-separated)

  2. Edit ${CYAN}.collection.env${RESET} with target collection:
     - CONTRACT_ADDRESS
     - MINT_FUNCTION
     - MINT_PRICE
     - PLATFORM (or leave 'auto')

  3. Run the bot:
     ${GREEN}node index.js${RESET}

  4. For dry run (no real tx):
     Set ${CYAN}DRY_RUN=true${RESET} in .env

${BOLD}Tips:${RESET}
  - Use DRY_RUN=true to test without spending gas
  - Use SIMULATE=true (default) to simulate before sending
  - Check logs/ folder for detailed per-wallet logs
  - Set LOG_LEVEL=debug for verbose output
