Trying to learn vcO - no actions in the workflow

Hi,

first off - i'm a newbie and I'm trying to learn how to create workflows in Orchestrator.

I've had my lab setup (vCenter 5.1 on a windows machine with Orchestrator thrown in). Now, I'm trying to follow this youtube link  Developing Your First VMware vCO Workflow (part 1) - YouTube

but i get stop at the part of adding Action Step because there's no action Image may be NSFW.
Clik here to view.

Not sure what I'm doing wrong. Let me know what I'm missing.

Also, if you guys have resource I should check out to get my feet wet fast with vCO, throw it in.

Thanks !
