I downloaded Yii and am currently running through the screencasts, and it creates a demo app that is parallel to the Yiiroot app. I am going to put my app under source control with git, and would like to know whether you ever make any changes in the Yiiroot folder, and if that should be placed in the git repository. So (following the screencast names) should webroot be the root of the git repository, or webroot/demo
