Question of creating a "hello world" project of newton

[xtty]

i have a question of creating a basic project.
I was using the lib in packages/Win32/release and the header files in /packages.
is this enough?

but why i saw the tutorial used many other header files? is it in source of newton? Am I must using it, too?
what is a newton project must be include?
i need help.
I am sorry for my bad English.

The two main header you have to include is newton.h and jointlibrary.h(if you want to use joint library).
The tutorial had made some user-defined classes and functions, such as the rigid.h, it had packed all the functions and operations that was used to create a rigid body in a several simple functions.
So, basically, in the tutorial, all the header that project has included, except the newton.h and jointlibrary.h, is not the part of the engine source code. They just show how to use the engine.
