vidmgr - Is there a guide for dummies?

So, I need a step-by-step on how to get vidmgr up and running on my base Roamio. I'm not a complete dunce, I have pyTivo installed and operational, and running as a service on a WHSv1, but vidmgr just seems confusing to me.



Can anyone 'walk me through it like I'm 80'? lol. :D
