Download Include File

https://github.com/taranais/NTPClient/archive/master.zip

Click here to download the NTP Client library. You should have a .zip folder in your Downloads
Unzip the .zip folder and you should get NTPClient-master folder
Rename your folder from NTPClient-master to NTPClient
Move the NTPClient folder to your Arduino IDE installation libraries folder
Finally, re-open your Arduino IDE
