jME3 - States

How should I manage states in jME3? I have seen a few things referring to AppState (I think that is correct) but I cannot find any documentation about this. Could someone please point me in the right direction. Thanks.

The AppStates are for making different states (MainMenu, Game, InGameMenu).

You find a small example in the jME tests:

You should use AbstractAppState for the differents states in your game.

I hope this helps.
