# Alpha Sentiment Engine — Docker Compose
# ===========================================
# This starts Redis (our message queue) in a Docker container.
#
# Think of it as: "Install the order board on the kitchen wall"
#
# HOW TO USE:
#   docker-compose up -d       ← start Redis (runs in background)
#   docker-compose ps          ← check it's running
#   docker-compose down        ← stop Redis
# ===========================================
