 - Callback functions are functions passed as an argument to a calling function.
 - Callback functions must meet the specification of the calling function.
-- These callbacks are all synchronous, meaning they all must return a value.
 
-## 1. Check if the grocer's service is online
+## 1. Notify with a successful message
 
-- Use the imported API function `checkStatus` in your function.
-- Pass a callback function to `checkStatus`. It should expect to receive a string argument.
-- Return the result from the `checkStatus` API function.
+- Use the imported API function `notify` in your function.
+- Pass an object to `notify`. It should have a property of `message`. Think about what the message value should be.
+- Pay attention to the JSDoc type hint -- the function should not return a value.
 
-## 2. See if the grocer has some fruit
+## 2. Notify with an error message
 
-- Use the imported API function `checkInventory` in your function.
-- Create the query _object_ to pass as an argument.
-  - Follow the template in the instructions.
-- Pass along the callback function to the `checkInventory` API function.
-- Return the result from the `checkInventory` API function.
+- Use the imported API function `notify` in your function.
+- Pass another object to `notify`. It should have a property of `message`. The message value should differ from the last part.
+- Pay attention to the comments [JSDoc] above the function definition:
+  - The function should not return a value.
 
-## 3. Create a callback to buy fruit if the inventory is available
+## 3. Place an order to buy fruit
 
-- If the `err` argument is not null, throw a new error using `err`'s message.
-  - See [Error()][mdn-error-constructor]
-- if the `err` is null, ignore it and just respond to the value of `isAvailable`
-  - This pattern is sometimes called a [`Node.js`-style callback][node-js-callback].
-- Return the action determined by `isAvailable`
+- Use the already imported `order` function.
+- Pay attention to the JSDoc type hints -- the function should receive 3 arguments and not return a value.
+- Reuse the previously created callbacks as arguments to the order function.
 
-## 4. Put it all together
+## 4. Refactor your work into a more concise function
 
-- Reuse the functions you have already written, composing them together.
-- Return the value of the callback function.

+- Reuse the functions from the previous tasks.
+- Pay attention to the JSDoc type hints -- the function should receive 2 arguments and not return a value.
+- Combine the arguments into an object representing the query to the grocer to place an order.
