I've found some issues with the spanish translation:
-Instead of Firmas SHASUMS de los arvhivos de versiones, it should be Firmas SHASUMS de los archivos de versiones
-Instead of Building Node.js from source on supported platforms, it should be Compilando Node.js del código fuente en las plataformas soportadas

@francoFerraguti wouldnt it be better:
Compilando Node.js desde el código fuente en las plataformas soportadas
than
Compilando Node.js del código fuente en las plataformas soportadas

I added the missing translation in #1642, but in the page, the content is still in English. I only changed the content in a markdown file, do I need to do something else?

Thanks (:
