 ## systemd
 
 The units in [`packaging/systemd/`](packaging/systemd/) assume a dedicated
 `wgcloak` user, `/usr/bin/wgcloak`, and configuration under `/etc/wgcloak/`.
+With the supplied units, use `/run/wgcloak-client/wgcloak.sock` for client
+commands and `/run/wgcloak-server/wgcloak.sock` for server commands, for
+example `wgcloak stats --socket /run/wgcloak-client/wgcloak.sock`.
 Review the paths and enabled listeners before installing. The server unit
 contains an optional, commented `CAP_NET_BIND_SERVICE` setting for ports below
 1024. Normal operation needs neither `CAP_NET_ADMIN` nor `CAP_SYS_ADMIN`.
