Find a video step by step

two weeks ago I bought my WDTV hub, but searching the internet I have seen some people do wonders with this unit. I would like to find a video that gives me step by stephow to put or work with: Theme, thumb, temples. 

the few videos I’ve seen are very air, a lot of foam and little chocolate almost say nothing, knowing that many do not know the steps as detailed as they may know thatwhenever they have played with technology, but others do not know . 

I believe that a picture is worth a thousand words. 

please help me to reach my WDTV Wonderful hub, I want to see it as beautiful as yours, the self can do wonders with mine.
