 ## How to use it
 
+### Test
+
+A test example is provided, which will output the battery information on the screen.
+
+First, you may need to:
+
+ * unload the *ftdi_sio* module, so the device is detected as a serial-usb device:
+
+> ``` sudo rmmod ftdi_sio```
+
+ * load the *pcspkr* module, so the motherboard buzzers makes sound when alarms are enabled:
+> ``` sudo modprobe pcspkr```
+
+Then you can run the example and see the battery status information on the screen.
+
+> ``` ./bin/battery_monitor_test```
+
+### Library
+
 To use this library in an other library or application, in the CMakeLists.txt file, first it is necessary to locate if the library has been installed or not using the following command
 
-``` FIND_PACKAGE(<library name>) ```
+> ``` FIND_PACKAGE(<library name>) ```
 
 In the case that the package is present, it is necessary to add the header files directory to the include directory path by using
 
-``` INCLUDE_DIRECTORIES(${<librray name>_INCLUDE_DIR}) ```
+> ``` INCLUDE_DIRECTORIES(${<librray name>_INCLUDE_DIR}) ```
 
 and it is also necessary to link with the desired libraries by using the following command
 
-``` TARGET_LINK_LIBRARIES(<executable name> ${<library name>_LIBRARY}) ```
+> ``` TARGET_LINK_LIBRARIES(<executable name> ${<library name>_LIBRARY}) ```
