Rules of the Kuromasu puzzle

Add black squares to the grid (only in the empty spaces) so that each number equals the count of white squares that are directly in line (horizontally and vertically) with that number's square, including the numbered square itself. Black squares cannot share an edge, and all remaining white squares must be connected orthogonally.
