 ### CSV Files!
+- Update the `Account` class to be able to handle all of these fields from the CSV file used as input.
+  - For example, manually choose the data from the first line of the CSV file and ensure you can create a new instance of your Account using that data
 - Add the following **class** methods to your existing `Account` class
   - `self.all` - returns a collection of `Account` instances, representing all of the Accounts described in the CSV. See below for the CSV file specifications
   - `self.find(id)` - returns an instance of `Account` where the value of the id field in the CSV matches the passed parameter
