Due board absent from "Tools > Boards" menu

Hello Can you help me please I bought an Arduino Due board; but whene uploading the code, I have not found the Due board in the menu : "Tools > Boards" Please note that I use Arduino IDE 1.6.5 Thank you for yor help Best regards

To use the Arduino Due you need to install the support files. This can be done by installing the "Arduino SAM boards" package within the boards manager.

Indeed. Click on Tools > Boards > Boards manager, select arduino sam with support to arduino due and click install

Thank you
