 We strongly encourage you to write your own styles for your accordions, but we've published these two starter stylesheets to help you get up and running:
 ```js
 // 'Minimal' theme - hide/show the AccordionBody component:
-import 'react-accessible-accordion/dist/fancy-example.css';
+import 'react-accessible-accordion/dist/minimal-example.css';
 
 // 'Fancy' theme - boilerplate styles for all components, as seen on our demo:
-import 'react-accessible-accordion/dist/minimal-example.css';
+import 'react-accessible-accordion/dist/fancy-example.css';
 ```
 
 We recommend that you copy them into your own app and modify them to suit your needs, particularly if you're using your own `className`s.
