Consider more detailed explanations

Reported from a learner via email:

It was a little difficult to understand as the syntaxes were not explained and I did not understand well what exactly was going on. Later, in order to use it for my project I started reading out the documentation and I understood GitHub Actions really well. The Documentation has each and every thing explained in little details and I found it perfect.

Suggest that a little more information could be added in the Beginner Course as it will get the people more interested and will motivate junior developers and new students.
