+ *************************************************************
+  This example runs directly on NodeMCU.
+
+  Note: This requires ESP8266 support package:
+    https://github.com/esp8266/Arduino
+
+  Please be sure to select the right NodeMCU module
+  in the Tools -> Board menu!
+
+  For advanced settings please follow ESP examples :
+   - ESP8266_Standalone_Manual_IP.ino
+   - ESP8266_Standalone_SmartConfig.ino
+   - ESP8266_Standalone_SSL.ino
+
+  Change WiFi ssid, pass, and Blynk auth token to run :)
+  Feel free to apply it to any other example. It's simple!
