No styles.xml file when I created a new project

I've just started developing android applications with Android Studio, I've watched couple of tutorial videos so I'm not very good at it, one of the tutorial videos used a file called `styles.xml` which is in `res/values`, but when I went to that folder, I didn't find the `styles.xml` file, I thought it may have glitched and not generated itself once I created my project, can somebody please help me?
