This may be a stupid question, but why does the latest version of Magento (without sample data, downloaded from http://magento.com) not include any files within the app directory? I successfully installed, but when looking at the code there is only app/design/frontend & app/design/adminhtml directories but nothing inside. All the other folders in the root directory have the expected files.
Seems strange as everything is working on the admin. This is for 2.1.5
