 After the matrix has been wired on both sides, the next step is to
 connect the microcontroller. The TMK firmware has the rows in pins D0,
-D1, D2, and D3 of the microcontroller. You'll need to connect the rows
+D1, D2, and D3 of the microcontroller.

+|------------+----+----+----+----|
+| row number |  1 |  2 |  3 |  4 |
+|------------+----+----+----+----|
+| pin number | D0 | D1 | D2 | D3 |

+You'll need to connect the rows
 from both the left and right sides into the proper pin. There are more
 columns than rows, so I used ribbon cable to bring the column
 connections back to the microcontroller from the outside in. The
 columns go to pins F0, F1, E6, C7, C6, B6, D4, B1, B0, B5, and
-B4. It's important to realize that when you flip over the board
+B4.

+It's important to realize that when you flip over the board
 in order to solder it, you have to flip over the schematic in your
 mind too. If you count your columns from the left, you'll get them
 backwards. (Which I actually did for the first half.)
