 # Instructions
 
-The diamond kata takes as its input a letter, and outputs it in a diamond
-shape. Given a letter, it prints a diamond starting with 'A', with the
-supplied letter at the widest point.
+The diamond kata takes as its input a letter, and outputs it in a diamond shape.
+Given a letter, it prints a diamond starting with 'A', with the supplied letter at the widest point.
 
 ## Requirements
 
-* The first row contains one 'A'.
-* The last row contains one 'A'.
-* All rows, except the first and last, have exactly two identical letters.
-* All rows have as many trailing spaces as leading spaces. (This might be 0).
-* The diamond is horizontally symmetric.
-* The diamond is vertically symmetric.
-* The diamond has a square shape (width equals height).
-* The letters form a diamond shape.
-* The top half has the letters in ascending order.
-* The bottom half has the letters in descending order.
-* The four corners (containing the spaces) are triangles.
