Install from scratch

Get the last raspbian image and flash it to your sdcard using Win32DiskImager for exemple.

To enable ssh, create a file named ssh in the boot partition of the sdcard. (https://www.raspberrypi.org/documentation/remote-access/ssh/)

Connect to the raspberry pi using ssh and use sudo raspi-config to enable the camera (/5/P1/ yes) and set an hostname to your pi. A reboot is needed.

Enable your wifi connection if needed by editing </etc/wpa_supplicant/wpa_supplicant.conf> using the command : wpa_passphrase <ssid> [passphrase]

Launch the file with : wpa_cli -i wlan0 reconfigure
