You can rearrange the pieces by dragging them to one of the marked squares. After setting up your starting position click the "Send" button. Rabbits will automatically be placed on the empty squares.

Once both sides have been setup, the pieces can begin moving. Just place the mouse over a piece to move and then click on one of the arrows. After moving the pieces click the "Send" button.

The red arrow buttons: < and > can be used to undo and redo the steps taken.
