<?xml version="1.0"?>

 <layout version="0.1.0">

  <helloworld_index_index>
   <reference name="root">
    <action method="setTemplate"><template>page/1column.phtml</template></action>
          </reference>
   <reference name="content">
             <block type="helloworld/helloworld" name="hello" template="helloworld/helloworld.phtml"/>
         </reference>
  </helloworld_index_index>

 </layout>
 
 

2. Create template file app/design/frontend/M4U/default/template/helloworld/helloworld.phtml and write down
