+
+> ReactOS is a free and open-source operating system based on the best design
+> principles found in the Windows NT architecture. Written completely from
+> scratch, ReactOS is not a Linux-based system and it shares none of the UNIX
+> architecture. The main goal of the ReactOS project is to provide an operating
+> system which is binary compatible with Windows. This will allow Windows
+> applications and drivers to run as they would on a Windows system. Additionally,
+> the look and feel of the Windows operating system is used, such that people
+> accustomed to the familiar user interface of Windows would find using ReactOS
+> straightforward. The ultimate goal of ReactOS is to allow people to use it as
+> an alternative to Windows without the need to change software they are used to.
