+This is a library for the HTU21D-F Humidity + Temp sensor
+
+Designed specifically to work with the HTU21D-F in the Adafruit shop 
+  ----> https://www.adafruit.com/products/1899
+
+These displays use I2C to communicate, 2 pins are required to interface
+Adafruit invests time and resources providing this open source code, 
+please support Adafruit and open-source hardware by purchasing 
+products from Adafruit!

+
+Check out the links above for our tutorials and wiring diagrams 
+
+To download. click the ZIP button in the top-middle navbar, 
+rename the uncompressed folder Adafruit_HTU21DF. 
+Check that the Adafruit_HTU21DF folder contains Adafruit_HTU21DF.cpp and Adafruit_HTU21DF.h
+
+Place the Adafruit_HTU21DF library folder your arduinosketchfolder/libraries/ folder. 
+You may need to create the libraries subfolder if its your first library. Restart the IDE.
+
+We also have a great tutorial on Arduino library installation at:
