Unable to correct code from tutorial, suggestions for step 1

[micdahl]

When clicking on 'Improve this code' on the tutorial setup, I see markdown code which is not identical to the content of the page. Because of this I was not able to create a pull request for the corrections I had to make to get Step 1 running.

So I write down the changes in code I had to make to come through step 1 at this place:

in 1.10:
remove line 222 (typography.scss does not exist in the nodes_module)

in 1.12:
add .woff2-mapping for all roboto-... fonts

in 1.13:
add import { BrowserModule } from '@angular/platform-browser';
and change imports to:

  imports: [
    IonicModule.forRoot(MyApp),
    BrowserModule
  ],
