It's very simple. When the EC is tuned in, just point the camera to the spot you want to meter and press green button to set exposure. Then capture the shot(s).
But first you need to test out which EC you can use with your camera. +2 - +2.5 stops is usually where it will be (including safety margin).
Then it also depend on which exposure mode you want to use for green button. P-mode is default, but I prefer Tv-shift so I set aperture and green button set shutter speed. ETTR works best at base ISO, so I usually don't change it. And when light get low it can be better to use traditional metering.
To be safe it can be good to set it up as a 3 shot bracketing for with +- 0.5 - 1 stop. It's not always the default EC that will be the best shot.
When you got everything set up you can save that as a user mode so you don't have to fiddle with the settings next time you want to use ETTR metering.
