 Please note running **mbusd** on default Modbus TCP port (502) requires root privileges!

+Configuration file:
+-------------------
+**mbusd** can read the configuration from a file specified by `-c` command line flag.
+Please see [example configuration file](conf/mbusd.conf.example)
+for complete list of available configuration options.
+
+systemd:
+---------------
+
+**mbusd** has [systemd](https://wiki.archlinux.org/index.php/systemd) support.
+The build system detects whether the system has systemd after which `sudo make install`
+installs the `mbusd@.service` file on systems with systemd active.
+
+The **mbusd** service can be started via:
+
+	# systemctl start mbusd@<serial port>.service
+
+where `<serial port>` is serial port device name (like `ttyUSB0`).
+
+**mbusd** started by systemd will read its configuration from file named `/etc/mbusd/mbusd-<serial port>.conf`.
+This way it's possible to run multiple **mbusd** instances with different configurations.
+
+To see the **mbusd** service status:
+
+	# systemctl status mbusd@<serial port>.service
+
+To monitor the **mbusd** service:
+
+	# journalctl -u mbusd@<serial port>.service -f -n 10
+
+To start the **mbusd** service on system boot:
+
+	# systemctl enable mbusd@<serial port>.service
+
+Please check systemd documentation for other usefull systemd [commands](https://wiki.archlinux.org/index.php/systemd)
