+ * explicitly in the code.
+ *
+ * In addition, this example allows you to enter your Adafruit IO username and key

+ *
+ * To use this example, setup a feed called "myfeed".  When the ESP8266 or ESP32
+ * microcontroller starts, join the "WiFi Setup" SSID and you should be presented
+ * with the config portal.  If the config portal does not automatically start you
+ * can browse to http://192.168.4.1 to access it
+ *
+ * Select the SSID and enter the password for WiFi Access in the config portal.
