# Easiest path — paste this into your own Hermes:
#   "Clone https://github.com/coolthor/hermes-bridge into ~/hermes-bridge,
#    run its install.sh, then show me the pairing QR so I can connect my phone."
#
# Or run it yourself:
#   git clone https://github.com/coolthor/hermes-bridge ~/hermes-bridge
#   bash ~/hermes-bridge/install.sh

✓ Done. On your phone:
    open HermesApp → 連線 → 掃描 QR Code → scan the QR on screen.
Next time, just tell your Hermes: 「連接手機」 and it shows the QR again.
