Thanks for starting the work on these!

Ideally, we'd love to get native speakers' eyes on these translations before merging them in to ensure that they're correct. It would also be great if you could add to the description the languages you've translated and how you created these translations.

For these translations, I used Google Translate and the Cambridge Dictionary websites as the main tools also I've mentioned the languages which i have translated and I’m happy to incorporate any additional feedback. Let me know if you need any further information or adjustments from my side!

[raclim]

Awesome, thanks so much for adding these! If you know any folks who are proficient in those languages feel free to tag them! I'll try to do so as well!
