## <a name="help_page"></a> Help page

**Help** page is implemented as extensible container that can be dynamically filled with tabs.
On smaller screens the tabs transform into dropdown menu.

Navigation to the **Help** page can be done using **help** state or **/help** route. 
Child state specifies the tab that shall be activated. If child set is not set, it opens the default tab
configured in **pipHelp** provider.

### Usage

```javascript
pipSideNavProvider.sections([{
    links: [
        { title: 'Help', url: '/help' }
    ]
}]);
```
