Tutorial to use the script:
apt-get install git -y
git clone https://github.com/andrediashexa/RaspberryChromiumAutoStart.git
cd RaspberryChromiumAutoStart
chmod a+x raspberrychromiumautostart
./raspberrychromiumautostart
After running this commands, paste the URL that you want to Chromium open when it autostart, then reboot your raspberry to test.
The Chromium will open on FullScreen Mode (not KIOSK mode). Use F11 to window it back.
If you need to change the URL, just run the script again.
