[Theme: Sampression Lite] Translating The theme

Hi people, I really liked the look of sampression-lite. But I am having a problem localizing it and translating it. I manage to create the po and mo files for portuguese pt_BR, using Poedit, yet they do not work once uploaded. I found it confusing for theme not to have a language folder or an pot file inside the template. Does anybody had the same problem? Any tips on how to fix it?
