+   Inkplate6FLICK_Simple_Deep_Sleep example for Soldered Inkplate 6FLICK
+   For this example you will need USB cable and Soldered Inkplate 6FLICK.
+   Select "Soldered Inkplate 6FLICK" from Tools -> Board menu.
+   Don't have "Soldered Inkplate 6FLICK" option? Follow our tutorial and add it:
+   https://soldered.com/learn/add-inkplate-6-board-definition-to-arduino-ide/
+
+   This example will show you how you can use low power functionality of Inkplate board.
+   Inkplate will wake every 20 seconds change content on screen.
+
+   NOTE: Because we are using deep sleep, everytime the board wakes up, it starts program from begining.
+   Also, whole content from RAM gets erased, so you CAN NOT use partial updates.
