I wouldn't advise doing it if you're unsure so don't shout if it goes wrong... Not sure of a link but I can expain...
Put firmware.zip in your adb/fastboot tools folder on computer
Connect to computer, debugging switched on on phone.
Open command prompt and cd to location of your adb/fastboot tools.
type in adb reboot bootloader
then type fastboot oem rebootRUU
then fastboot flash zip firmware.zip
<---- or whatever name your firmware.zip is called
then you should get a warning. DO NOT DISCONNECT YOUR PHONE OR DO ANYTHING RANDOM
type in fastboot flash zip firmware.zip
then it should work and say done
type fastboot reboot-bootloader
to ensure your mainver changed and hboot upgraded etc
type fastboot reboot
and you're set.....
But as I said this can be risky so unless you're confident you know what you're doing then don't do it.
Oh and if it's a custom firmware.zip then you'll need S-OFF if you're not already and if it's not a custom zip or you're not S-OFF then be wary that if it doesn't work you could be stuck with firmware that doesn't work as you wont be able to downgrade back to your old one after you flash it.
