# Alpine 5G Router – install/deploy scripts and config to this device
# Run from repo root: ./scripts/install.sh

# Rev: 2  (see REVISION in repo root)
#
# NOTE: As of Rev 2, 5g-webgui handles both Web GUI AND 5G connection management.
#       The standalone 5g-router service is kept for manual/fallback use but is
#       NOT enabled by default. Use 5g-webgui instead.
