+## Non Coordinated Components
+
+In most cases you'll create compound components that have a model and share information across sub
+components. However, in the case where information doesn't need to be shared, you'll create a non
+coordinated component. These components often represent some styled element with no associated role
+or behavior and don't rely on state and events such as a `Card`, `Flex` or `Button` component. Use
+`createComponent` factory function in these scenarios.
+
+### `createComponent`
+
+Use `createComponent` when you want to create a rendered element with _no behavior_. This is useful
+for elements that you want to use for styling purposes like container elements, or sub components
+that are simple rendered elements. This utility function will wrap your component in a
+`React.ForwardRef` and allow you to add sub components as well.
+
+```tsx
+export const Card = createComponent('div')({
+  displayName: 'Card',
+  subComponents: {
+    Heading: CardHeading, // this is also using createComponent
+  },
+  Component: ({children, ...elemProps}: CardProps, ref, Element) => {
+    return (
+      <Box as={Element} {...elemProps} ref={ref}>
+        {children}
+      </Box>
+    );
+  },
+});
+```

 ## Models
 
 A model is composed of state and events. The shape of the model used by components looks like this:
