 Introduction:
 -------------
 
-Subsurface was started because of a lack of viable dive log software
-on Linux. It turns out that the resulting software was easily ported
-to Windows and Mac, but it clearly is a native Linux program first.
-The program is under active development and at version 3.0 it is
-already very usable for divers with supported dive-computers.
+Subsurface is an open source divelog program that runs on Windows, Mac
+and Linux. It was started because of a lack of viable dive log
+software on Linux. It then turned out that the resulting software was
+fairly easily ported to Windows and Mac and today great effort is put
+into making it a viable application on all three platforms.
 
-In this manual the Suunto Vyper will be used for all examples.
+The program is under active development and at version 3.0 it compares
+favorably to many other programs in this market.

+While the list of supported dive computers is very long, in this
+manual the Suunto Vyper will be used for all examples.
