Creating your first project tutorial

Silverstripe Version: 4.5

Question:
I am a bit confused regarding one of the first tutorials: creating your first project. Is that tutorial up to date? Or is there another tutorial for creating themes? https://www.silverstripe.org/learn/lessons/v4/creating-your-first-project
I have downloaded the latest version of SS. But the structure seems quite different.

Can you guys help?
