Hello Stefan!
Thank you very much for you reply! I downloaded the res.cls file do I need to save in a certain folder to make it work?

I'm using Latex in my mac. I'm trying to compile a resume.tex file and I get the following:
./resume.tex:2: LaTeX Error: File `res.cls' not found. [\usepackage]
I'm actually a noob in Latex and Mac, so I assume that that's something elemental but I can't figure it out.
