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