Meaningful Headlines instead of Tutorial 1, 2, etc

[axbusch]

Hi,

one minor suggestion:

on each tutorial page you have a section
Learning Objectives - e.g. Task Priorities, Mutexes etc
in the readme.

Can you use these headline in the index of the repo instead of "Tutorial 1", "Tutorial 2" etc. Then you don't have to click on every tutorial headline to know what is hidden inside
