raspi-config

default login: pi/raspberry
via "sudo raspi-config"
- german-locale + german-keymap
- activate sshd (and i2c for pi-usv)
- reboot (for keyboard)
- may disable sound (for stuff that uses gpio like matrix) (/boot/config.txt, dtparam=audio=off)
apt install -y vim curl htop mc tmux git

manual stuff

configure wlan
- sudo iwlist wlan0 scan | grep FR36
- sudo nano /etc/wpa_supplicant/wpa_supplicant.conf network={ ssid="FR36" psk="testingPassword" }
- sudo wpa_cli reconfigure
- we should get a IP now: ifconfig wlan0
