+If the i2c address of the LCD Display Module is different from the default address `0x27`, the `address` property 
+needs to be set. If the address of the module is unknown the `i2cdetect` tool can be used which is part 
+of the `i2c-tools` package on Raspbian. 
+Note, the addresses output by the tool are hexadecimal numbers. To set the address property of the plugin 
+accordingly, the number has to be provided as a string preceded by '0x'.
