Hi apogio,

a translation of your tutorial to Naija language has been posted and I commented there to add the detail that after making changes to the /boot/config.txt file usually the Raspi needs a reboot to apply those changes to take effect.

Maybe you could add this detail for Raspi newbies, too?
