+Hello World Example
+===================
+
+This example demonstrates Hello World example running on top of Helidon container and using Helidon connector as a client
+implementation for testing. JAX-RS resource returns the usual text `Hello World!`.
+
+Contents
+--------
+
+The mapping of the URI path space is presented in the following table:
+
+URI path             | Resource class      | HTTP methods | Notes
+-------------------- | ------------------- | ------------ | --------------------------------------------------------
+**_/helloworld_**    | HelloWorldResource  |  GET         |  Returns `Hello World!`
+
+Running the Example
+-------------------
+
+Run the example as follows:
+
+>     mvn clean compile exec:java
+
+This deploys the example using [Helidon](http://helidon.io/) container.
