The ui looks basically the same except for more white than blue.
Follow the guides on how to root.
Won't lay it all out for you since there a million guides and so on.
But you will need to unlock the bootloader. That will wipe all your data off your device. Everything will be gone.
After that you just need to boot up and put the su. Zip on the device. Reboot into the bootloader again flash a custom recovery. Or just boot it. Then flash the zip you put on the phone with the custom recovery.
That's it. Done. Now stock rooted.
If this don't make sense to you. It probably won't. Read the quides in general.
