 The **North American Numbering Plan (NANP)** is a telephone numbering system used by many countries in North America like the United States, Canada or Bermuda. All NANP-countries share the same international country code: `1`.
 
 NANP numbers are ten-digit numbers consisting of a three-digit Numbering Plan Area code, commonly known as *area code*, followed by a seven-digit local number. The first three digits of the local number represent the *exchange code*, followed by the unique four-digit number which is the *subscriber number*.

 The format is usually represented as
-```
+
+```text
 (NXX)-NXX-XXXX
 ```

 where `N` is any digit from 2 through 9 and `X` is any digit from 0 through 9.

 ### 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/phone-number/PhoneNumber.m
+```
+
+You can find the Exercism workspace by running `exercism debug` and looking for the line beginning
+with Workspace.
