 Determine if a number is perfect, abundant, or deficient based on
 Nicomachus' (60 - 120 CE) classification scheme for natural numbers.
 
 The Greek mathematician [Nicomachus](https://en.wikipedia.org/wiki/Nicomachus) devised a classification scheme for natural numbers, identifying each as belonging uniquely to the categories of **perfect**, **abundant**, or **deficient** based on their [aliquot sum](https://en.wikipedia.org/wiki/Aliquot_sum). The aliquot sum is defined as the sum of the factors of a number not including the number itself. For example, the aliquot sum of 15 is (1 + 3 + 5) = 9
 
-- **Perfect**: aliquot sum = number 
+- **Perfect**: aliquot sum = number
   - 6 is a perfect number because (1 + 2 + 3) = 6
   - 28 is a perfect number because (1 + 2 + 4 + 7 + 14) = 28
 - **Abundant**: aliquot sum > number
   - 12 is an abundant number because (1 + 2 + 3 + 4 + 6) = 16
   - 24 is an abundant number because (1 + 2 + 3 + 4 + 6 + 8 + 12) = 36
 - **Deficient**: aliquot sum < number
   - 8 is a deficient number because (1 + 2 + 4) = 7
   - Prime numbers are deficient

 Implement a way to determine whether a given number is **perfect**. Depending on your language track, you may also need to implement a way to determine whether a given number is **abundant** or **deficient**.
 
 ## Setup
 
 There are two different methods of getting set up to run the tests with Objective-C:

 - Create an Xcode project with a test target which will run the tests.
 - Use the ruby gem `objc` as a test runner utility.
 
 Both are described in more detail here: http://exercism.io/languages/objective-c

 ### Submitting Exercises
 
 When submitting an exercise, make sure your solution file is in the same directory as the test code.
 
-For example, if you're submitting `Bob.m` for the Bob exercise, the submit command would be something like `exercism submit <path_to_exercism_dir>/objective-c/bob/Bob.m`.
+The submit command will look something like:
+
+```shell
+exercism submit <path-to-exercism-workspace>/objective-c/perfect-numbers/PerfectNumbers.m
+```
+
+You can find the Exercism workspace by running `exercism debug` and looking for the line beginning
+with Workspace.
