Cache Problems

Any updates I make to my CSS files don't show up in browser even after I clear my browsers cache. I noticed this in the Perch documentation, "If you set PERCH_PRODUCTION_MODE to PERCH_PRODUCTION in your config then they will not cache and you should see changes immediately."

However, I didn't see anything like that in my config file. Would I have to add that? If so what exactly would I be adding?
