# vscc — open patient-monitor telemetry stack (research/education use only).
#
# Single-file install, no repo checkout needed:
#   curl -O https://raw.githubusercontent.com/chsbusch-dot/vscc-mqtt-server/main/docker-compose.yml
#   MONITOR_IP=192.168.1.215 docker compose up -d
# Then open http://<this-host>/ in a browser.
#
# Runs anywhere Docker (Compose V2) runs: Linux, macOS, Windows/WSL2,
# Raspberry Pi. Uses prebuilt images from ghcr.io/chsbusch-dot.
# Developers: use vscc-docker-compose.yml in the repo to build from source.
#
# WARNING — patient data stays local: do not expose these ports beyond your
# controlled network; captured telemetry may constitute PHI.
