 ##Overview
-AutoRest generates a client type based on a name defined in the specification (see [swagger specification parsing](swagger.md) overview). The generated client inherits from [`ServiceClient<T>`](../Microsoft.Rest/ClientRuntime/ServiceClient.cs).
+AutoRest generated code can currently work in a variety of .NET project types including:
+
+  * Desktop applications (.NET 4.0 and .NET 4.5)
+  * Web applications (.NET 4.0 and .NET 4.5)
+  * Windows Phone (8.1)
+  * Windows Store App (8.1)
+  * Portable Class Libraries
+
+Before being able to compile generated code *Microsoft.Rest.ClientRuntime* nuget package needs to be added to the project. This package will include several dependent packages based on project profile such as Newtonsoft Json.Net.
+
+After that, the client can be used as such:
+```
+var myClient = new MyClient();
+var salutation = myClient.GetGreeting();
+Console.WriteLine(salutation);
+```
+
+##Initialization
+AutoRest generates a client type based on a name defined in the specification (see [swagger specification parsing](swagger.md) overview). The generated client inherits from [`ServiceClient<T>`](../Microsoft.Rest/ClientRuntime/ServiceClient.cs) base type available in *Microsoft.Rest.ClientRuntime* nuget package. 
+
+Client is generated with a number of constructors: 
+
+* Default constructor that sets Base URL of the client to the one specified in the specification and configures the client to use anonymous authentication
+* Constructor that accepts Base URL
+* Constructor that accepts Credentials object (see [authentication](#Authentication) section)
+
+##Authentication
+The client will support authentication if it was generated using [-AddCredentials](cli.md) flag.

 We now access the REST API with the fact that `GetGreeting` will throw an exception if the response is not a 200 OK, we can access the REST API with very little code (see [using generated clients](Documentation/using-clients.md) for details).
 ```
 var myClient = new MyClient();
-var salutation = myClient.GetGreeting().Body();
+var salutation = myClient.GetGreeting();
 Console.WriteLine(salutation);
 ```
 Running the console app shows the greeting retrieved from the service API.
