Create Spanish version of the guide

[jmatthiesen]

Would love to have a Spanish version of the README created, for now a general "ES" version would be great. Ideally we could have more specific locales (e.g. es-ES (Spain) and es-MX (Mexico)), but that does increase the complexity for maintenance.

I can help with this, I am a native Spanish speaker from Mexico.

Thanks, @mahomedalid - this would be a great help! I've assigned it to you for now, but please let me know if you can't do this after all.
