Setting up a Raspberry Pi for headless WiFi setup is done in two simple steps:

Place an empty file named ssh on the boot partition of the SD-card

Create the file wpa_supplicant.conf in the boot partition with the following contents:

ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
country=DE #set your country code here

network={
 ssid="SSID"
 psk="WIFI PASSWORD"
}
