Additional details

This is by far the most complex tutorial, and you will see a lot of editing in the MD file. I stuck to 2 principles:

1. Fix so each part of the tutorial can be run without errors (only 1 part will generate an error, but I added an admonition explaining how to solve it; Cfr. line 801).
2. Fix based on the code examples and current text content; the new strings follow the wording already employed and I didn't add new code, I just copied it!

After doing the tutorial, I noticed that the result is not the same as the most current version of the code. I realized that after seeing some bugs in the final result. But as I understand, there are plans to come back and reshape this tutorial. Meanwhile, this PR allows working with the tutorial with less friction.

Please let me know if you need some changes.

Thank you! It is time for me to develop my own apps, hahah.
