+#### Editing Existing Models
+
+If you want to modify an existing model or remove it from the list:
+
+1. Open `app/Enums/ModelName.php` and locate the model case you want to change.
+2. Update the case value or name along with the corresponding `getName`,
+   `getDescription` and `getProvider` matches.
+3. If you remove a case, delete it from the enum and from each of these match
+   statements.
+4. Save the file and run your tests to verify everything still works as
+   expected.
