 Welcome to Looking Glass's documentation!
 =========================================
 
+Looking Glass is an open-source application that allows the use of a KVM
+(Kernel-based Virtual Machine) configured for VGA PCI Pass-through
+without an attached physical monitor, keyboard or mouse. This is the
+final step required to move away from dual booting with other operating
+systems for legacy programs that require high-performance graphics.
