+## Headless version
+
+There is a qcma_cli binary that doesn't need a X session running (useful for servers).
+The daemon provides minimal interaction via dbus. Here are some usage examples:
+
+#### Send a signal to refresh the database
+
+```
+dbus-send --session --type=method_call --dest=org.qcma.HeadlessManager /HeadlessManager org.qcma.HeadlessManager.refreshDatabase
+```
+
+#### Send a signal to stop the daemon
+
+```
+dbus-send --session --type=method_call --dest=org.qcma.HeadlessManager /HeadlessManager org.qcma.HeadlessManager.stop
+```
+
+#### Receive confirmation when the database finished updating
+
+```
+dbus-monitor "type='signal',sender='org.qcma.HeadlessManager',member='databaseUpdated'"
