+    Inkplate10_Youtube_Subscriber_Counter example for Soldered Inkplate 10
+    For this example you will need only USB cable and Inkplate 10.
+    Select "e-radionica Inkplate10" or "Soldered Inkplate10" from Tools -> Board menu.
+    Don't have "e-radionica Inkplate10" or "Soldered Inkplate10" option? Follow our tutorial and add it:
+    https://soldered.com/learn/add-inkplate-6-board-definition-to-arduino-ide/
+
+    This example show how to use Google API to show info about some youtube chhannel.
+    You need to register on https://developers.google.com/ and get API key of any kind so, you
+    can use your API key in API call. That key you should copy in variable api_key.
+    Second thing you need to get ID of any youtube channel and copy it in channel_id variable.
+    You can get ID by going on any youtube channel profile and copy part of URL link after
+    https://www.youtube.com/channel/ (so just some random text after last backslash).
+
+    IMPORTANT:
+    Make sure to change wifi credentials below
+    Also have ArduinoJSON installed in your Arduino libraries, download here: https://arduinojson.org/
