Hi,
Galician is a language spoken primarily in Galicia, but with a historical presence that extends to the bordering regions of the northwestern Iberian Peninsula. It is the native language of nearly 2.5 million people in Galicia and thousands more in the Galician diaspora around the world, particularly in Latin America.

I have been dedicating myself to web development and training for several years. And I would like to contribute to this project by translating the content into my language: Galician.

The issue requests a Galician translation of the tutorial, but names no files, tests, or translation entry point. First inspect the repository's contribution and localization structure to determine the translation scope; done means the agreed tutorial content is available in Galician and follows the project's conventions.
