 The value holds the number of ESP32 module restarts. Since it is written to NVS, the value is preserved between restarts.
 
-Example also shows how to check if read / write operation was successful, or certain value is not initialized in NVR. Diagnostic is provided in plain text to help track program flow and capture any issues on the way.

 Detailed functional description of NVS and API is provided in [documentation](http://esp-idf.readthedocs.io/en/latest/api/nvs_flash.html).
