+Installing from a GitHub Clone
+1. If you are installing ATutor from a GitHub clone, rather than an ATutor bundled distribution, follow the usual installation and upgrade instructions at the link above.
+2. Before running the Installer, you will need to create an empty config file. To create the file, from the ATutor base directory, issue the command 
+touch include/config.inc.php
+3. Then follow the instruction given by the Installer.
 
+GitHub Basics
+If you wish to have code you've developed added to the ATutor public source code, you will need to understand a few Git basics.
