There is no exact page available but you can use WCF utitlity available with Visual Studio 2010.

(I'm literally paraphrasing these links)
Add a description attribute to method, and probably WebGet as well, like:
[OperationContract]
[WebGet(UriTemplate="/template1", BodyStyle = WebMessageBodyStyle.Bare)]
[Description("Description for GET /template1")]
SyndicationFeedFormatter GetTemplate1();
Expose the endpoint via web.config...
<endpointBehaviors>
<behavior name="RESTEndpointBehavior">
<webHttp enableHelp="true"/>
</behavior>
</endpointBehaviors>
<!-- ... -->
<services>
<service behaviorConfiguration="RESTWebServiceBehavior" name="RESTWebService"> <endpoint address="" kind="webHttpEndpoint" behaviorConfiguration="RESTEndpointBehavior" contract="IHello" />
<!-- ... -->
</service>
</services>
...or in code
using (WebServiceHost host = new WebServiceHost(typeof(Service), new Uri("http://localhost:8000/Customers")))
{
host.AddServiceEndpoint(typeof(ICustomerCollection), new WebHttpBinding(), "");
host.Description.Endpoints[0].Behaviors.Add(new WebHttpBehavior { EnableHelp = true });
// ...
}
