+====== 2.3 System configuration after Setup of Operating System ======
+===== System Update =====
+Update your system:
+<code>
+sudo bash
+apt update && apt upgrade && reboot now
+</code>
+===== System configuration =====
+==== Unique hostname ====
+set up a unique hostname - especially, if you have multiple Pi's. for simplicity, i would suggest ''scannerNN'' - replacing //NN// with a number:
+<code>
+sudo hostnamectl set-hostname scannerNN
+sudo nano /etc/hosts
+hostnamectl
+</code>
+==== Timezone ====
+Not mandatory, but i would suggest to set UTC:
+<code>
+sudo timedatectl set-timezone UTC
+timedatectl
+</code>
+==== WiFi country ====
+In case you want to use WiFi
+<code>
+sudo iw reg get
+sudo iw reg set DE
+sudo iwlist wlan0 frequency
+</code>
+you should replace above ''DE'' with //your// wifi country; check https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2
+==== Localization / Languages ====
+<code>
+sudo dpkg-reconfigure locales
+</code>
+i would suggest to select ''en_US.UTF-8'' as default language
