 When the story renders in the UI, Storybook executes each step defined in the `play` function and runs the assertions without the need for user interaction.
 
+## Custom render functions
+
+Starting in Storybook 6.4, you can write your stories as JavaScript objects, reducing the boilerplate code you need to generate to test your components, thus improving functionality and usability. `Render` functions are helpful methods to give you additional control over how the story renders. For example, if you were writing a story as an object and you wanted to specify how your component should render, you could write the following:

+/>
+
+<!-- prettier-ignore-end -->
+
+When Storybook loads this story, it will detect the existence of a `render` function and adjust the component rendering accordingly based on what's defined.
+
 ## Storybook export vs. name handling
 
 Storybook handles named exports and the `name` option slightly differently. When should you use one vs. the other?

 Let's define a story for our `Badge` component:
 
-<Story name="positive">
-  {{
+<Story 
+  name="positive"
+  render={() => ({
     template:`<Badge status="positive">Positive</Badge>`,
-  }}
-</Story>

 We can drop it in a `Canvas` to get a code snippet:
 
 <Canvas>
-  <Story name="negative">
-    {{

+    name="negative"
+    render={() => ({
       template: `<Badge status="negative">Negative</Badge>`,
-    }}
-  </Story>
+    })} />
 </Canvas>
 
 We can even preview multiple stories in a block. This
 gets rendered as a group, but defines individual stories
 with unique URLs and isolated snapshot tests.
