We don't think that software should require manuals or help files.  A computer screen should be familiar and inviting from the first glance.  You won't find a lot of dropdown menus with obscure options in our software - just obvious and friendly controls that make you want to jump in and go.
If it isn't second nature, then it isn't yesware.
The Jaguar XK8 does come with an instruction manual.  The manufacturer recommends that you read it in it's entirety before driving off the dealer's lot.  Nobody ever does.
