+### Styling Highcharts and GlobalOptions
+If you want to use the extra stylings like the one in [highcharts.js demo](http://www.highcharts.com/demo/dark-unica), you will need to get the Highchart static members, from Highcharts' `node_modules`. Note that in `angular2-higchcharts` we have **already** included `highcharts` as `node_modules`, so you do not need to do `npm install highcharts` anymore. A wrapper is infact provided that you can use to access to the native API.
+
+Make sure you import the correct variables. Examples are given below
+
+To use the typings:
+
+    import * as HighChartsTypings from 'highcharts';
+
+To use the Highchart's StaticMember wrapper (do not be confused with the typings):
+
+    import {Highcharts} from 'angular2-highcharts/dist/HighChartsWrapper'
+
+#### Set background image
+```TypeScript
+import { Component } from '@angular/core';
+import * as HighChartsTypings from 'highcharts'; // this is imported by typescript just for the typings, from index.d.ts
+import {Highcharts} from 'angular2-highcharts/dist/HighChartsWrapper'//this ons is required by node, from highcharts.js' node_modules
+
+
+@Component({
+    selector: 'simple-chart-example',
+    template: `
+        <chart [options]="options"></chart>
+    `
+})
+export class App {
+    constructor() {
+        this.options = {
+            title : { text : 'simple chart' },
+            series: [{
+                data: [29.9, 71.5, 106.4, 129.2],
+            }]
+        };
+        Highcharts.wrap(Highcharts.Chart.prototype, 'getContainer', function (proceed) {
+            proceed.call(this);
+            this.container.style.background = 'url(http://www.highcharts.com/samples/graphics/sand.png)';
+        });
+    }
+
+    options: HighChartsTypings.Options;
+}
+```
+#### Use Roboto font in global settings
+```TypeScript
+import { Component } from '@angular/core';
+import * as HighChartsTypings from 'highcharts'; 
+import {Highcharts} from 'angular2-highcharts/dist/HighChartsWrapper'
+

+            }]
+        };
+
+        // Load the fonts
+        Highcharts.createElement('link', {
+        href: 'https://fonts.googleapis.com/css?family=Roboto:400,700',
+        rel: 'stylesheet',
+        type: 'text/css'
+        }, null, document.getElementsByTagName('head')[0]);
+
+        let defaultGlobalOptions:HighChartsTypings.GlobalOptions;
+
+        defaultGlobalOptions = {
+            chart: {
