-# Include [Flex Layout](https://github.com/angular/flex-layout) for [Angular Material](https://material.angular.io)
-
-Include Angular Material as detailed above.
-
-Install the `@angular/flex-layout` library and add the dependency to package.json...
-```bash
-npm install --save @angular/flex-layout
-```
-
-Import the Angular Flex-Layout NgModule into your app module...
-```javascript
-//in src/app/app.module.ts 
-
-import { FlexLayoutModule } from '@angular/flex-layout';
-// other imports 
-
-@NgModule({
-  imports: [
-    ...
-    FlexLayoutModule.forRoot()
-  ],
-  ...
-})
-```
-
-Run `ng serve` to run your application in develop mode, and navigate to `http://localhost:4200`
-
-Add the following to `src/app/app.component.css`...
-```css
-.header {
-  background-color: lightyellow;
-}
-
-.left {
-  background-color: lightblue;
-}
-
-.right {
-  background-color: pink;
-}
-```
-
-To verify flex-layout has been set up correctly, change `src/app/app.component.html` to the following...
-```html
-<div fxLayout="column">
-
-  <div class="header" fxLayout="row" fxLayoutAlign="space-between center">
-
-    <h1>
-      {{title}}
-    </h1>
-
-    <button md-raised-button>
-      Angular Material works! 
-      <md-icon>done</md-icon>
-    </button>
-
-  </div>
-
-  <div fxLayout="row">
-
-    <div class="left" fxFlex="20">
-      LEFT: 20% wide
-    </div>
-
-    <div class="right" fxFlex>
-      RIGHT: 80% wide
-    </div>
-
-  </div>
-</div>
-```
-
-After saving this file, return to the browser to see the very ugly but demonstrative flex-layout.
-
-Among what you should see are - a light yellow header that is the entire width of the window, sitting directly atop 2 columns. Of those 2 columns, the left column should be light blue, and 20% wide, while the right column is pink, 80% to start, and will flex with window (re)size.
