 # Instructions
 
-Add the mine counts to a completed Minesweeper board.
+Your task is to add the mine counts to empty squares in a completed Minesweeper board.
+The board itself is a rectangle composed of squares that are either empty (`' '`) or a mine (`'*'`).
 
-Minesweeper is a popular game where the user has to find the mines using numeric hints that indicate how many mines are directly adjacent (horizontally, vertically, diagonally) to a square.
+For each empty square, count the number of mines adjacent to it (horizontally, vertically, diagonally).
+If the empty square has no adjacent mines, leave it empty.
+Otherwise replace it with the adjacent mines count.
 
-In this exercise you have to create some code that counts the number of mines adjacent to a given empty square and replaces that square with the count.
-
-The board is a rectangle composed of blank space (' ') characters.
-A mine is represented by an asterisk (`*`) character.
-
-If a given space has no adjacent mines at all, leave that square blank.
