How I can use digital communication to present digital communication??

I'm having  hard time righting this I'm not going to lie.. I feel like there are so many options on ways to show how a digital communication tool works that it kind of makes my brain hurt at 11 in the evening I think the best way to show how to work my digital communication skill would be make a video of someone making an account with yahoo messenger and then demonstration how different things work and how it can attribute to their day to day things.  this is the best way because so many people learn visually now a days that it really makes the most sense but in order to reinforce the lesson on how to use the yahoo messenger I would over lay the video that i make or find with a vocal voice over and narrate what the person is doing in the video that way people are not as confused .. I know that if someone were to show me a video without someone talking about whats going on then im going to be really confused but anyway Yahoo messanger is really simple but it can look really complicated so the video would be very helpful to people so that they know what all the links do ect
