 # Example Mesh application for mbed OS
 
-This applications tries to be the simplest one that utilizes our Mesh networking stack.
+This applications is the simplest one to utilizes our Mesh networking stack. All it does is join the unsecure *6LoWPAN-ND* network.
 
-Basically only thing it does, is to join unsecure *6LoWPAN-ND* network.

 ## Changing the radio driver
 
-In order to run 6LoWPAN-ND network, you need working RF driver for Nanostack.
