+Setting up the Maven Wrapper on an Application
+==============================================
+
+This is the code that shows the configurations of maven wrapper on a SpringBoot project.
+
+### Requirements
+
+- Maven
+- JDK 7
+
+### Running
+
+To build and start the server simply type
+
+```bash
+$ ./mvn clean install
+$ ./mvn spring-boot:run
+```
+
+Now with default configurations it will be available at: [http://localhost:8080](http://localhost:8080)
+
+Enjoy it :)
