Headless WiFi Setup, Raspberry Pi 3, Raspbian Jessie

It is possible to push latest Raspbian Jessie image on SD card and set WiFi credentials even the OS is not booted yet.

This particular example is tested on 2017-03-02-raspbian-jessie-lite together with Raspberry Pi 3

To do it so I need to open boot partition and create new file wpa_supplicant.conf with content:

network={
ssid="NameOfNetwork"
psk="W3rySecuRePasw0rd"
key_mgmt=WPA-PSK
}

Also I like to enable SSH. Just put an empty ssh file on boot partition:
