But why? I‘m working with it daily and what I learned is to read the docs properly. Usually it‘s me not reading correctly. There is some advanced stuff that‘s not covered in the docs, but not necessary to build an app.
That's exactly the point: a documentation should be comprehensive, i.e. it for each class and each method it should describe exactly what the method does, including all parameters etc. The Laravel "documentation" is a tutorial, i.e. it describes what you should do for the most common use cases in a style designed to be read from beginning to end. Which has its uses too, but as documentation, it's pretty lacking...
