+## Features
+* Worlds least efficient Sudoku solver
+* Ability to assign a number of CPU cores to this task
+* Split workloads among several computers
+
 ## Usage
 To use the sudoku solver, run the binary with all the parameters available:
 ```
 Usage of ./sudoku-funpark:
+  -numcpu int
+    	Number of CPU cores to assign to this task. (default 12)
+  -part int
+    	Process part x in n parts. Cannot be lower than 1, or higher than specified in split. (default 1)
   -row1 string
     	1st row of the sudoku puzzle. (default "000000000")
   -row2 string
@@ -31,6 +40,8 @@ Usage of ./sudoku-funpark:
     	8th row of the sudoku puzzle. (default "000000000")
   -row9 string
     	9th row of the sudoku puzzle. (default "000000000")
+  -split int
+    	Split the tasks in n parts. This depends on the availability of the first row. (default 1)
 ```
 
 Instead of using the 3x3 blocks with 3x3 digits, it uses horizontal rows from top to bottom.
