For me as a former Ubunut user  it will be kind of interesting what changes you have made under the hood when you planed and developed deep inside. Is there any document or even a YouTube video that explains that in detail.

Another example, could be how the very cool dip in the logo of the current release is done. Is this still a Plymouth theme. And I am shure there far more examples like that Where can I start my journey to get quite familiar with deepin  if I just switched from Ubuntu?
