Good starting point!
There are parts that I find a bit hard to understand, in general, learn section should be easy as a first approach, and if necessary, link other sections that go deeper.

Excellent work with the diagrams!

Almost there!

@eshaben Thanks for your input. I tried to cover all your comments; let me know if I missed anything.
Related to the diagrams, I also think that the color palette can be misleading sometimes. I tried to modify some elements, but I couldn't.

There is some problem in the way that Mermaid renders the diagram when it is integrated with mkdocs.
The best thing that I could do was modify the background of the diagrams so that they are easier to understand.

This are some examples:

And this is the PR with the background chance
