 Standby Wake from RTC Demo for Portenta H7 
-    This example demonstrates how to  wake up the Portenta H7 from standby mode using the included RTC (Real Time Clock).
-    The device will go to sleep for 10 second and then stay awake for another 10. When the device is awake you will see the board's blue LED turned on. 
-    Effectively, you will get the same effect as with blink. 
+This example demonstrates how to  wake up the Portenta H7 from standby mode using the included RTC (Real Time Clock).
+The device will stay awake for ~5 seconds, then go to sleep for 10 second. When the device is awake you will see the board's blue LED turned on. 
+Effectively, you will get the same effect as with blink. 
 
-    On the Portenta H7 with the peripherals turned off you can expect around 300uA of current consumption in standby mode.
-    The example also turns off the peripherals before going to sleep and turns them back on after waking up.
-    Usage:
-        - Make sure you are running the latest version of the Renesas Core
-        - Select the Portenta H7 board from the Tools men
-        - Select the Portenta H7 USB port from the Tools menu
-        - Upload the code to your Portenta H7

+Note: You need to upload this sketch to both cores, the M7 and the M4 for it to work.
+      You can do so by selecting the M7 core and then the M4 core from the Tools menu in the "Target core" section.
