If you are prone to seizures, skip ahead to 17:00 as the presenter begins the video by jumping around from page to page to page to page to page to page in a completely unorganized scattershot manner. At 17:30 he begins, "To create a theme, you will just create a new project for it..." and the useful information begins to manifest.
absolutely correct the presenter spends more than half of the time in selecting the theme? why we need the content and what exactly the videos does and reach the goal instead of spending the time on selecting and choosing the theme.
