+# Storybook Addon Outline
+
+Storybook Addon Outline can be used for visually debugging CSS layout and alignment inside the preview in [Storybook](https://storybook.js.org). Based on [Pesticide](https://github.com/mrmrs/pesticide), it draws outlines around every single element in the preview pane.
+

+
+## Usage
+
+Requires Storybook 6.1 or later. Outline is part of [essentials](https://storybook.js.org/docs/react/essentials/introduction) and so is installed in all new Storybooks by default. If you need to add it to your Storybook, you can run:
+
+```sh
+npm i -D @storybook/addon-outline
+```
+
+Then, add following content to [`.storybook/main.js`](https://storybook.js.org/docs/react/configure/overview#configure-your-storybook-project):
+
+```js
+module.exports = {
+  addons: ['@storybook/addon-outline'],
+};
+```
+
+You can now click on the outline button in the toolbar to toggle the outlines.
