Upfront is very difficult from scratch

So currently for my clients I build website using the Xtheme from Themeco....

I find it more beneficial if I start using all WPMU products for my clients, It will keep me from paying for the platform per client and i will have the peace of mind knowing everything is compatible. Not to mention WPMU has great plugins.

My problem is I just cant get the hang of Upfront at all!

Can someone please point me in the direction of a video tutorial or a step by step instructions on how to get started with upfront from scratch. I even scoured Youtube to no prevail and its starting to frustrate me as I would really love to start making sites using Upfront only.

Thank you for your help
