### Documentation

Documentation can be found [Storybook's docs site](https://storybook.js.org/docs).

### Examples

Here are some featured examples that you can reference to see how Storybook works: <https://storybook.js.org/showcase>

Storybook comes with a lot of [addons](https://storybook.js.org/docs/react/configure/storybook-addons) for component design, documentation, testing, interactivity, and so on. Storybook's API makes it possible to configure and extend in various ways. It has even been extended to support React Native, Android, iOS, and Flutter development for mobile.

| [notes](https://github.com/storybookjs/deprecated-addons/tree/master/addons/notes) | Annotate Storybook stories with notes                      |
| [contexts](https://storybook.js.org/addons/@storybook/addon-contexts/)             | Addon for driving your components under dynamic contexts   |

In order to continue improving your experience, we have to eventually deprecate certain addons in favor of new, better tools.

If you're using info/notes, we highly recommend you to migrate to [docs](addons/docs/) instead, and [here is a guide](addons/docs/docs/recipes.md#migrating-from-notesinfo-addons) to help you.

If you're using contexts, we highly recommend you to migrate to [toolbars](https://github.com/storybookjs/storybook/tree/next/addons/toolbars) and [here is a guide](https://github.com/storybookjs/storybook/blob/next/MIGRATION.md#deprecated-addon-contexts) to help you.

### Development scripts

Storybook is organized as a monorepo using [Lerna](https://lerna.js.org/). Useful scripts include:

#### `yarn bootstrap`

> Installs package dependencies and links packages together - using lerna

#### `yarn lint`

> boolean check if code conforms to linting rules - uses remark & eslint

- `yarn lint:js` - will check js
- `yarn lint:md` - will check markdown + code samples
- `yarn lint:js --fix` - will automatically fix js

#### `yarn test`

> boolean check if unit tests all pass - uses jest

- `yarn run test --core --watch` - will run core tests in watch-mode
