Zencoder tutorial skipping certain steps

I’m currently going through this tutorial - http://factore.ca/on-the-floor/65-automatically-encode-video-to-html5-formats-with-zencoder

What exactly do I need to do where it says:

“Now you need to add a method that will accept notifications from the Zencoder service to the controller, which I’m assuming is called videos_controller. (This is also where you’ll have your new, edit, create, update, etc. methods for videos, which I’m assuming you are fully capable of creating yourself - you will need at minimum new and create actions so you can upload the original videos).”

Unfortunately, I’m not yet fully capable of creating this myself.
