 Find the optimal number of persons to assign to a pre-defined list of shifts, under a requirement of persons per period 
 of day and capacity restrictions
 
+#### Example:
 
 ```python
 from pyworkforce.shifts import MinAbsDifference
 
-# Columns are an hour of the day, rows are the days
+# Rows are the days, each entry of a row, is an hour of the day (24).
