+You have a grid of white squares, all of which contain numbers. Your task
+is to colour some of the squares black (removing the number) so as to satisfy
+all of the following conditions:
+
+\b No number occurs more than once in any row or column.
+
+\b No black square is horizontally or vertically adjacent to any other black
+square.
+
+\b The remaining white squares must all form one contiguous region
+(connected by edges, not just touching at corners).

+Left-clicking on an empty square will colour it black; left-clicking again
+will replace the number. Right-clicking will add a circle (useful for
+indicating that a cell is definitely not black).
+
+You can also use the cursor keys to move around the grid. Pressing the
+return or space keys will turn a square black or add a circle respectively,
+and pressing the key again will replace the number or remove the circle.
+
+(All the actions described in \k{common-actions} are also available.)
