9-steps Tutorial: German Whispers

Here is a tutorial sudoku teaching the German Whispers (GW) constraint and aimed at first-timers. It is accessible, though not the easiest puzzle. When following the steps, it is build to showcase some common GW logic you will find in almost any GW sudoku there is! However, if you feel like it, or for more experienced solvers, feel free to solve it any way you like, there are no rules! (Except these ones...)

Rules: Normal sudoku rules. Along a line, adjacent digits must differ by 5 or more.
