+Usage: sudo ./pi/install_roverd.sh [options]
+
+Options:
+  -b, --binary <path>   Path to the roverd binary (default: dist/roverd)
+  -c, --config <path>   Source config to install if /etc/roverd.yaml is missing
+                        (default: pi/roverd/roverd.sample.yaml)
+      --mediamtx        Also install mediaMTX unit/config (requires pi/mediamtx files)
+  -h, --help            Show this help text
+
+The script must run from the repository root and as root (sudo). It will:
+  * create system users/groups if needed
+  * install /usr/local/bin/roverd and /etc/roverd.yaml
+  * install /etc/systemd/system/roverd.service and enable the service
+  * optionally install mediaMTX config/unit when --mediamtx is set
