Hello,
The Tutorial Portal has been shut down at the begining of this year.
It was decided to replace it by the Online-Course Section which offers a more flexible possiblility to create online Trainings.
Please have a look here:
Online Courses
Free content is only visible when logged in. More info about this on the bottom of the Page itself.
The Automation Studio is a very powerfull tool, with many features like programming, motion, visualisation, safety, communication … I would suggest you start by lerning in sections, which are most interessting for you.
Greetings
Michael
