I've attached the (slim) Users Guide for the Day-0 Pack here. This document is visible at the automationstore under workflow-help.
This workflow runs under the OnCommand Workflow Automation (aka; WFA) product. WFA is available running on a Wndows Server (2008/2012) or a Redhat Linux server (and Win7 if that option is helpful). WFA normally requires the companion OnCommand Unified Manager (OCUM) product but I'm not 100% clear if it (OCUM) is 'absolutely' required to use this workflow. Most clents have/use OCUM for other purposes. If so, then after installing WFA there is just a quick setup process to link WFA with OCUM.
Once WFA is available, you can easily 'Import' this workflow into WFA and run it ... and edit it if needed.
PS: The automationstore says the Day-0 workflow requires WFA 3.1P2 or later so it should work under WFA 3.1p2 or the newer WFA 4.0.
