 We are going to do the `Transform` step of an Extract-Transform-Load.
 
 ### ETL
+
 Extract-Transform-Load (ETL) is a fancy way of saying, "We have some crufty, legacy data over in this system, and now we need it in this shiny new system over here, so
 we're going to migrate this."
 
 (Typically, this is followed by, "We're only going to need to run this
 once." That's then typically followed by much forehead slapping and
 moaning about how stupid we could possibly be.)
 
 ### The goal
+
 We're going to extract some scrabble scores from a legacy system.
 
 The old system stored a list of letters per score:
 
 - 1 point: "A", "E", "I", "O", "U", "L", "N", "R", "S", "T",

 - 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/etl/Etl.m
+```
+
+You can find the Exercism workspace by running `exercism debug` and looking for the line beginning
+with Workspace.
