 A great tool to use when writing stories is the [Storybook Controls addon](https://storybook.js.org/addons/@storybook/addon-controls). Ideally props should be exposed by using this addon, which provides a graphical UI to interact dynamically with the component without needing to write code. Avoid using [Knobs](https://storybook.js.org/addons/@storybook/addon-knobs) for new stories, as this addon is deprecated.
 
-The default value of each control should coincide with the default value of the props (i.e. it should be `undefined` if a prop is not required). A story should, therefore, also explicitly show how values from the Context System are applied to (sub)components. A good example of how this may look like is the [`Card` story](https://wordpress.github.io/gutenberg/?path=/story/components-card--default) (code [here](/packages/components/src/card/stories/index.js)).
