+
+Modbus extensions requires native Modbus RTU/TCP library to be installed nearby Beremiz.
+Following directory structure is expected:
+<Parent directory>
+  "beremiz"
+  "Modbus"
+
+If Modbus library is installed elsewhere, then place corresponding paths
+in CFLAGS/LDFLAGS in project settings.
+
+For GNU/Linux to install Modbus library in parent directory run following commands:
+$ hg clone https://bitbucket.org/mjsousa/modbus Modbus
+$ cd Modbus
+$ make
+
+After that Modbus extension is ready to be used in Beremiz projects.]]></xhtml:p>
