A Queen, 4 Kings, and 2 Rooks

Arrange 1 Queen, 4 Kings and 2 Rooks on a standard 8x8 chessboard, so that every square (occupied or not) is under attack by at least 1 chess-piece.

You have the following additional information about the pieces: The Queen is an all-attacking piece, i.e. it can attack any other piece (King or Rook) from its position. On the other hand, no King can attack any other chess-piece. Rooks are friendly and won't attack each other.
