 The goal is to write an implementation of `getArnieQuotes()` that passes all unit tests.
 
-To pass the unit tests, `getArnieQuotes()` must perform the following each URL passed in;
+To pass the unit tests, `getArnieQuotes()` must perform the following on each passed URL
 
 1. Perform a HTTP GET on the URL
 2. If the HTTP status code of the response is 200, push an object to the results array with a single key `"Arnie Quote"` and the HTTP response body's `message` property as the key's associated value.
 3. If the HTTP status code of the response is not 200, push an object to the results array with a single key `"FAILURE"` and the HTTP response body's `message` property as the key's associated value.
 
-Finally, the `getArnieQuotes()` function must return the overall results array.
+Finally, the `getArnieQuotes()` function must return a promise that resolves to the overall results array.

 ## Tips
 * Only modify the `get-arnie-quotes.js` file.
 * You may introduce additional internal functions in `get-arnie-quotes.js`
-* Exploring all of the code files may provide useful hints.
+* Exploring all of the code files may provide you with useful hints.
 * We are most impressed with readable code that works.
+* Keep your solution as simple as possible, input validation for `get-arnie-quotes()` is not required.
+* Code as if your `get-arnie-quotes()` function may one day be used against a real http implementation.
 
 ## Submission
 
-Once all unit tests pass, push your code upstream then send us the link to the github repo with your solution.
