# Sub2API Docker Compose Configuration
# =============================================================================
# Quick Start:
#   1. Copy .env.example to .env and configure
#   2. docker-compose up -d
#   3. Check logs: docker-compose logs -f sub2api
#   4. Access: http://localhost:8080
#
# All configuration is done via environment variables.
# No Setup Wizard needed - the system auto-initializes on first run.
