I have the ZC book and in Chapter 17, Advanced Customization, they talk about the template override system. Where are the files/directory to do Advanced Customization? I have been working on the admin side making changes to the modules but don't know where the directory is that contains the files to customize the look-and-feel of the site. This is so basic to most of you I'm sure that I was afraid to ask but the programmer I was working with did not work out and I decided to give it a try myself. Thank you.
