# Docker Compose Examples for Media Preview Generator
#
# Copy this file to docker-compose.yml and modify as needed.
# Choose ONE of the configurations below based on your setup.
#
# All settings (Plex, GPU, processing) are configured in the web UI at
# http://YOUR_IP:8080. settings.json in /config is the source of truth.
#
# Full configuration reference: docs/reference.md

# =============================================================================
# CONFIGURATION 1: GPU (Intel / AMD / NVIDIA)
# =============================================================================
# Covers all three GPU vendors in one service.
# Uncomment/modify the blocks for your hardware.
