-# Contributing to Storybook
-
-## Creating a new Story
-
-> A Story basically represents a single visual state of a component.
-
-To create a new story, create a new file located alongside the component you
-want to document on Storybook.
-
-See below an example of the structure:
-
-```
-core
-└── src
-    └── components
-        └── Progress
-            ├── Progress.tsx
-            └── Progress.stories.tsx
-```
-
-> _Note: make sure your component story file has the following format
-> componentName.stories.tsx_
-
-## Running locally
-
-Go to `packages/storybook`, run `yarn install` and install the dependencies,
-then run the following on your command line: `yarn start`
-

-
-_You should see a log like the image above._
-
-If everything worked out, your server will be running on **port 6006**, go to
-your browser and navigate to `http://localhost:6006/`. You should be able to
-navigate and see the Storybook page.
