+# Instructions
+
+Your task is to add flower counts to empty squares in a completed Flower Field garden.
+The garden itself is a rectangle board composed of squares that are either empty (`' '`) or a flower (`'*'`).
+
+For each empty square, count the number of flowers adjacent to it (horizontally, vertically, diagonally).
+If the empty square has no adjacent flowers, leave it empty.
+Otherwise replace it with the count of adjacent flowers.
+
+For example, you may receive a 5 x 4 board like this (empty spaces are represented here with the '·' character for display on screen):
+
+```text
+·*·*·
+··*··
+··*··
+·····
+```
+
+Which your code should transform into this:
+
+```text
+1*3*1
+13*31
+·2*2·
+·111·
+```

+# Introduction
+
+[Flower Field][history] is a compassionate reimagining of the popular game Minesweeper.
+The object of the game is to find all the flowers in the garden using numeric hints that indicate how many flowers are directly adjacent (horizontally, vertically, diagonally) to a square.
+"Flower Field" shipped in regional versions of Microsoft Windows in Italy, Germany, South Korea, Japan and Taiwan.
