Its good you have taken an intiative. But the quality of video on youtube "generally" isnt good. To see the commands you type in either zoom in on it while creating the video or create high quality videos and host'em on your own website.
And keep the background black for better visibility, nothing leafy
Moreover, add a brief description to your post on what you are trying to achieve in the video. So that people dont have to view it and then try to analyse on what you were trying do ?!
