Better page ordering

[Connie]

I am a newbie with GetSimple and I just can't figure out how to define the page order.
The first page is shown as the last page in the menu (left to right) or as the bottom page (top to down ordering of the menu)
As I as a user start to define the first page I assume this is the homepage and expect it at the first place in the menu

how to do this?

I miss a simple basic tutorial for users (not developers. designers), just a first how-to :=)
