"The English version is the original and authoritative version of the book. The Brazilian Portuguese and Spanish editions were translated using AI and have not yet undergone a full human technical review. They are published to make the material accessible to more readers, but they may contain translation mistakes, awkward wording, or technical inaccuracies introduced during translation.

If something in a translated edition seems unclear, inconsistent, or technically questionable, please refer to the English version as the source of truth. Help with reviewing and improving the translations is very welcome (see Contributing below)."
