+Any raw assets you want to be deployed with your application can be placed in
+this directory (and child directories) and given a Build Action of "AndroidAsset".
+
+These files will be deployed with your package and will be accessible using Android's
+AssetManager, like this:
+
+public class ReadAsset : Activity
+{
+	protected override void OnCreate (Bundle bundle)
+	{
+		base.OnCreate (bundle);
+
+		InputStream input = Assets.Open ("my_asset.txt");
+	}
+}
+
+Additionally, some Android functions will automatically load asset files:
+
+Typeface tf = Typeface.CreateFromAsset (Context.Assets, "fonts/samplefont.ttf");

+Images, layout descriptions, binary blobs and string dictionaries can be included 
+in your application as resource files.  Various Android APIs are designed to 
+operate on the resource IDs instead of dealing with images, strings or binary blobs 
+directly.
+
+For example, a sample Android app that contains a user interface layout (main.axml),
+an internationalization string table (strings.xml) and some icons (drawable-XXX/icon.png) 
+would keep its resources in the "Resources" directory of the application:
+
+Resources/
+    drawable/
+        icon.png
+
+    layout/
+        main.axml
+
+    values/
+        strings.xml
+
+In order to get the build system to recognize Android resources, set the build action to
+"AndroidResource".  The native Android APIs do not operate directly with filenames, but 
+instead operate on resource IDs.  When you compile an Android application that uses resources, 
+the build system will package the resources for distribution and generate a class called "R" 
+(this is an Android convention) that contains the tokens for each one of the resources 
+included. For example, for the above Resources layout, this is what the R class would expose:
+
+public class R {
+    public class drawable {
+        public const int icon = 0x123;
+    }
+
+    public class layout {
+        public const int main = 0x456;
+    }
+
+    public class strings {
+        public const int first_string = 0xabc;
+        public const int second_string = 0xbcd;
+    }
+}
+
+You would then use R.drawable.icon to reference the drawable/icon.png file, or R.layout.main 
+to reference the layout/main.axml file, or R.strings.first_string to reference the first 
+string in the dictionary file values/strings.xml.

+gRPC C# on Xamarin
+========================
+
+EXPERIMENTAL ONLY
+-------------
+Support of the Xamarin platform is currently experimental.
+The example depends on experimental Grpc.Core nuget package that hasn't
+been officially released and is only available via the [daily builds](https://packages.grpc.io/)
+source.
+
+BACKGROUND
+-------------
+The example project supports Xamarin.Android and Xamarin.iOS
+
+For this sample, we've already generated the server and client stubs from [helloworld.proto][].
+
+PREREQUISITES
+-------------
+
+- The latest version Xamarin Studio or Visual Studio 2017 with Xamarin support installed.
+
+BUILD
+-------
+
+- Open the `HelloworldXamarin.sln` in Visual Studio (or Xamarin Studio)
+- Build the solution (Build -> Build All)
+
+Try it!
+-------
+
+You can deploy the example apps directly through Xamarin Studio IDE.
+Deployments can target both Android and iOS (both support physical device
+deployment as well as simulator).
