 Start out by adding the parent configuration to your pom.
 
     <parent>
-        <groupId>org.jboss</groupId>
-        <artifactId>jboss-parent</artifactId>
-        <version>6-beta-2</version>
+      <groupId>org.jboss</groupId>
+      <artifactId>jboss-parent</artifactId>
+      <version>6-beta-2</version>
     </parent>
 
 Depending on the needs of your build, you can customize the plugins and other settings using properties.
 For example, to override the default version of the maven-compiler-plugin, just set a property.
 
     <properties>
-        <version.compiler.plugin>2.3</version.compiler.plugin>
+      <version.compiler.plugin>2.3</version.compiler.plugin>
     </properties>
 
 Or override the default Java compiler source and target level used in the build.  Note the default level is 1.6.
 
     <properties>
-        <maven.compiler.target>1.5</maven.compiler.target>
-        <maven.compiler.source>1.5</maven.compiler.source>
+      <maven.compiler.target>1.5</maven.compiler.target>
+      <maven.compiler.source>1.5</maven.compiler.source>
     </properties>
 
 For the full list of properties, refer to the POM itself.
