I've noticed that theres no spanish translation yet, and I think is a basic one.

I would like to go ahead with this too.

Hi @siderio2 and thanks for reaching out!

There's an ongoing PR for Spanish translations: #282, maybe you can finish on it?

[siderio2]

I think so, will look how is ti going.

Thanks for this @siderio2! We've already got a ticket for this: #233 - you can move discussions to there if you'd like!
