First of all thanks!
All contributions will be accepted for the material under this source folder: the markdown document meant to be viewed by the tutorial audience will be generated from the html page contained under source.
The code of the presented module is purposefully extremely simple: I do not plan to change it.
On the other hand every correction in the testing process, or in the git phase will be welcome.
Markdown is not rendered always as I intended (even if the html is correct): it has some weird rendering in the tutorial-english.md
As English not my mother tongue, any English correction will be welcome too.
Translations will be gladly accepted.
