In your Razor View,
@Html.Resource("ResourceLabel", "ResourceName")
In the above code, replace ResourceLabel with the key and ResourceName with the type, you used to create the label in the Sitefinity CMS. Make sure Telerik.Sitefinity.Frontend.Mvc.Helpers namespace is imported in the view. i.e
@using Telerik.Sitefinity.Frontend.Mvc.Helpers;
Sample usage
<li><a href="/">@Html.Resource("Home", "PageResources")</a></li>
