+##WebServer Basic Example
+
+This example demonstrates a minimal Helidon WebServer application that starts an HTTP server and exposes simple routes.
+
+##Project Structure
+
+```
+webserver-basic/
+ ├── src
+ │   └── main
+ │       └── java
+ │           └── io/helidon/examples/webserver/basic/
+ │               ├── Main.java
+ │               └── GreetService.java
+ ├── pom.xml
+ └── README.md
+
+```
+##Build
+
+Use Maven to compile the project:
+
+mvn clean install
+
+Run
+
+Start the WebServer using:
+
+java -jar target/webserver-basic.jar
+
+
+The server will start on the default port (8080) unless configured otherwise.
+
+Exercise the Application
+
+After the application is running, you can call the available endpoints:
+
+Root endpoint
+curl -X GET http://localhost:8080
+
+Greet endpoint
+curl -X GET http://localhost:8080/greet
+
+Personalized greeting
+curl -X GET http://localhost:8080/greet/{name}
+
+
+This will return:
+{"message": "Hello {name}!"}
+
+Update the greeting
+curl -X PUT -H "Content-Type: application/json" \
+    -d '{"greeting": "Hola"}' \
+    http://localhost:8080/greet/greeting
+
+##Notes
+
+This example follows the standard Helidon project layout.
