 Baklava comes with an icon pack using SVG sprite images. The `Icon` component is used to render a given icon by name:
 
 ```tsx
-<Icon icon="assessment"/>
+<Icon icon="badge-assessment"/>
 ```
 
 This will render:
 
-<Icon icon="assessment" style={{ fontSize: '2rem' }}/>
+<Icon icon="badge-assessment" style={{ fontSize: '2rem' }}/>
 
 Icons by default will adapt to the current text styling. To resize an icon, change the `font-size` in CSS. Similarly, you can change the CSS `color` property to update the icon's color.
