Schengen visa via the Spanish embassy [duplicate]

I applied for a Schengen visa via the Spanish embassy. The visa was refused for two reasons:

(1) Justification for the purpose and conditions of the intended stay was not provided.

(2) information submitted regarding the justification for the purpose and condition of the intended stay was not reliable.

My question is if I appeal, what documentation do I need to provide. Also do I need to translate my write-up for the consulate to Spanish?
