Thanks to KitteninaBox and ValkyrieMoon to push me in the good direction! Finally... after only one year i prepared a more complete guide to the game (i really don't like to write the documentation ːsteammockingː )
The Guide is accessible by the in game tutorial, at the end if you click on next you will be redirected to an external website (switching to not full screen mode). I remind you that the tutorial open automatically for new players or you can open it by clicking on the "?" icon on the top of the screen.
I link it also here
