+Alternatively, ``host_info`` target can be used without enabling nxdiag application and reflashing to get information about system. 
+Target can work after configuration step and prints information about the NuttX and host systems.
 
 .. note:: Nxdiag requires Python 3.6 or later. On Linux distributions, the ``distro`` Python module is
           recommended as it provides more accurate information about the host system.
