It would be great if we could have Spanish translation on the website.

Describe the solution you'd like

Add a Spanish translation to the website.

Describe alternatives you've considered

None.

Additional context

There might be not so many people who know Spanish here, but I think it would be great to expand to more languages.
I'd also like to work on this 🙂 Spanish is my native language, so I think I'll do good. 😄

Cool, please continue your idea as we talk in discord :D

To add languages easier and make the process better, we can use Weblate. 😄
I maintain a website that uses Weblate as well as NextJS, so we can see a way to integrate it here. :)

This is kinda old, but I'll add the Spanish translation itself for now. 🙂
