The default compose files put the backend on a bridge network, where ARP only ever reaches the Docker gateway — so scans report IPs, ports and services but never a MAC. NET_RAW does not help: it grants raw sockets, not a place on the LAN. Rescan matching prefers MAC over IP, so this also makes a DHCP device reappear as a new inventory entry when its lease changes. None of this was documented anywhere. Adds an INSTALLATION.md section covering the network_mode: host fix, the Docker Desktop macOS/Windows limitation and the macvlan alternative, a pointer from the README scanner section, and a commented-out network_mode: host in both compose files so it is a one-line change. Reported in discussion #368. ha-relevant: no
