# Contribute by translating lessons We welcome translations for the lessons in this curriculum! > Note, please do not use Google Translate or other machine translation tools for translations, but rather use your own proficiency and manually translate the files. ## Guidelines There are folders in each lesson folder and lesson introduction folder which contain the translated markdown files. > Note, please do not translate any code in the code sample files; the only things to translate are README, assignments, and the quizzes. Thanks! Translated files should follow this naming convention: **README._[language]_.md** where _[language]_ is a two letter language abbreviation following the ISO 639-1 standard (e.g. `README.es.md` for Spanish and `README.nl.md` for Dutch). **assignment._[language]_.md** Similar to Readme's, please translate the assignments as well. **Quizzes** 1. Add your translation to the quiz-app by adding a file here: https://github.com/microsoft/Data-Science-For-Beginners/tree/main/quiz-app/src/assets/translations, with proper naming convention (en.json, fr.json). **Please don't localize the words 'true' or 'false' however. thanks!** 2. Add your language code to the dropdown in the quiz-app's App.vue file. 3. Edit the quiz-app's [translations index.js file](https://github.com/microsoft/Data-Science-For-Beginners/blob/main/quiz-app/src/assets/translations/index.js) to add your language. 4. Finally, edit ALL the quiz links in your translated README.md files to point directly to your translated quiz: https://red-bay-0a991ec0f.1.azurestaticapps.net/quiz/1 becomes https://red-bay-0a991ec0f.1.azurestaticapps.net/quiz/1?loc=id **THANK YOU** We truly appreciate your efforts!
