sudo raspi-config
# 1. Expand Filesystem
# 2. Change User Password => raspoid
# 3. Boot Options => Desktop Autologin (Desktop GUI, automatically logged in as 'pi' user)
# 4. (need to connect a keyboard to the RPi) Internationalisation Options => Change Keyboard Layout => ... Generic Azerty configured
# 5. Internationalisation Options => Change Timezone => Europe / Brussels
# 5. Enable Camera => Enable
# 6. Advanced Options => Hostname => raspoid
# 7. Advanced Options => I2C => Yes => Load by Default
# 8. Finish => Reboot now
