+  An Arduino library for the ESP8266 WiFi-serial bridge
+
+  https://www.adafruit.com/product/2282
+
+  The ESP8266 is a 3.3V device.  Safe operation with 5V devices (most
+  Arduino boards) requires a logic-level shifter for TX and RX signals.
+
+  Adafruit invests time and resources providing this open source code,
+  please support Adafruit and open-source hardware by purchasing
+  products from Adafruit!
