Default [Q] Translation to PT-BR

Hello all

I'd like to request the ROM to be added full translation to Portuguese (Brazil), Actually the ROM have this language but many things continue in english when PT-BR is selected. Is there a way i can help translate? I am not familiarized with github, so if i will need to work with it, i need a tutorial too.

By the way, the ROM is way fast than cyanogenmod 11, i dont know why but i felt this.
