+Distroshare Ubuntu Imager
 =========================
 
-Creates an installable live CD from an installed Ubuntu or derivative distribution
+This project is brought to you by distroshare.com.  Distroshare.com is 
+a new site for sharing customized open source operating system distributions.  
+Too often do users need to customize open source operating systems, 
+such as Ubuntu, to work correctly on their machines.  By distributing 
+a custom Ubuntu distro with the kinks worked out for your machine, you 
+would be helping others to run Ubuntu if they have the same machine.
+
+
+
+Distroshare Ubuntu Imager creates an installable Live ISO from an installed 
+Ubuntu or derivative distribution.
+
+It is a bash script, similar to Remastersys and its forks.  The script is 
+based on this tutorial: https://help.ubuntu.com/community/MakeALiveCD/DVD/BootableFlashFromHarddiskInstall. 
+
+To boot the ISO from a USB stick, you can use the dd command like this:
+
+dd if=isoimage.iso of=/dev/sdb bs=1M
+
+where sdb is your USB drive.  You should be able something similar on Mac OS X.
+You can also use UNetbootin: http://unetbootin.sourceforge.net/ to create a 
+bootable USB drive.
+
+Ubuntu Startup Disk creator won't be able to turn the iso into a bootable 
+usb drive since Distroshare Ubuntu Imager uses grub2 as the bootloader.
