# Deploy ReticulumHF to Pi - Gateway Installation
# Usage: ./deploy-to-pi.sh [pi-hostname-or-ip] [username]
#
# ReticulumHF turns a Raspberry Pi into a Reticulum gateway for HF radio.
# Use with Sideband app on your phone for messaging.
#
# Architecture:
#   [Phone/Sideband] --WiFi--> [Pi/ReticulumHF] --Audio--> [Radio] ~~~HF~~~
#
# This script performs a COMPLETE installation on a fresh Raspberry Pi OS.
