+## Introduction
+Tapeti is a wrapper for the RabbitMQ .NET Client designed for long-running microservices. It’s main goal is to minimize the amount of messaging code required, and instead focus on the higher-level flow.
+
+## Key features
+* Consumers are declared using MVC-style controllers and are registered automatically based on annotations
+* Publishing requires only the message class, no transport details such as exchange and routing key
+* Flow extension (stateful request - response handling with support for parallel requests)
+* No inheritance required
+* Graceful recovery in case of connection issues, and in contrast to most libraries not designed for services, during startup as well
+* Extensible using middleware
+
+## Show me the code!
+Below is a bare minimum message controller from the first example project to get a feel for how messages are handled using Tapeti.
+```csharp
+/// <summary>
+/// Example of a simple broadcast message used in the standard publish - subscribe pattern
+/// </summary>
+public class PublishSubscribeMessage
+{
+    [Required(ErrorMessage = "Don't be impolite, supply a {0}")]
+    public string Greeting { get; set; }
+}
+
+
+[MessageController]
+[DynamicQueue("tapeti.example.01")]
+public class ExampleMessageController
+{
+    public ExampleMessageController() { }
+
+    public void HandlePublishSubscribeMessage(PublishSubscribeMessage message)
+    {
+        Console.WriteLine("Received message: " + message.Greeting);
+    }
+}
+```
+
+More details and examples can be found in the documentation as well as the example projects included with the source.
