+## title: 'Storybook for Angular'
+
+You may have tried to use our quick start guide to setup your project for Storybook. If you want to set up Storybook manually, this is the guide for you.
+
+> This will also help you understand how Storybook works.
+
+## Starter Guide Angular
+
+Storybook has its own Webpack setup and a dev server.  
+The Webpack setup is very similar to [Angular CLI](https://cli.angular.io), but allows you to [configure it however you want](/configurations/custom-webpack-config/).
+
+In this guide, we are trying to set up Storybook for your Angular project.
+
+## Table of contents

+-   [Add @storybook/angular](#add-storybookangular)
+-   [Create the config file](#create-the-config-file)
+-   [Write your stories](#write-your-stories)
+-   [Run your Storybook](#run-your-storybook)
+
+## Create Angular project
+
+First of all, you need to prepare an Angular project. To do that, run:
+
+```sh
+npm i -g @angular/cli
+ng new your-angular-prj
+cd your-angular-prj
+```
+
+## Add @storybook/angular
+
+Next, install `@storybook/angular` to your project:
+
+```sh
+npm i --save-dev @storybook/angular
+```
+
+Then add the following NPM script to your package json in order to start the storybook later in this guide:
+
+```json
+{
+  "scripts": {
+    "storybook": "start-storybook -p 9001 -c .storybook"
+  }
+}
+```
+
+## Create the config file
+
+Storybook can be configured in several different ways. 
+That’s why we need a config directory. We've added a `-c` option to the above NPM script mentioning `.storybook` as the config directory.
+
+For the basic Storybook configuration file, you don't need to do much, but simply tell Storybook where to find stories.
+
+To do that, simply create a file at `.storybook/config.js` with the following content:
+
+```js
+import { configure } from '@storybook/angular';
+
+function loadStories() {
+  require('../stories/index.ts');
+}
+
+configure(loadStories, module);
+```
+
+That'll load stories in `../stories/index.ts`.
+
+Just like that, you can load stories from wherever you want to.
+
+## Write your stories
+
+Now you can write some stories inside the `../stories/index.ts` file, like this:
+
+```js
+import { storiesOf } from '@storybook/angular';
+import { action } from '@storybook/addon-actions';
+import { MyButtonComponent } from '../src/app/my-button/my-button.component';
+
+storiesOf('My Button', module)
+  .add('with some emoji', () => ({
+    component: MyButtonComponent,
+    props: {
+      text: '😀 😎 👍 💯',
+    },
+  }))
+  .add('with some emoji and action', () => ({
+    component: MyButtonComponent,
+    props: {
+      text: '😀 😎 👍 💯',
+      click: action('clicked'),
+    },
+  }));
+```
+
+Each story is a single state of your component. In the above case, there are two stories for the MyButton component:
+
+1.  story with `@Input()` property binding.
+2.  story with `@Input()` and `@Output()` property binding.
+
+## Run your Storybook
+
+Now everything is ready. Simply run your storybook with:
+
+```sh
+npm run storybook
+```
+
+Now you can change components and write stories whenever you need to.
+You'll get those changes into Storybook in a snap with the help of Webpack's HMR API.
