 First, create an Annotation with annotated with @javax.inject.Scope; Example:
 
-      :::java
-      @Scope
-      @Retention(RetentionPolicy.RUNTIME)
-      @Target({ElementType.TYPE,ElementType.METHOD,ElementType.FIELD})
-      public @interface ACustomScope {}
+    :::java
+    @Scope
+    @Retention(RetentionPolicy.RUNTIME)
+    @Target({ElementType.TYPE,ElementType.METHOD,ElementType.FIELD})
+    public @interface ACustomScope {}
     
 Second, create an Extension to add the scope and a context for it. Example:
 
-      :::java    
-      public class ACustomScopeExtension implements Extension, Serializable {
-	
-      	public void addACustomScope(@Observes final BeforeBeanDiscovery event) {
-      		event.addScope(ACustomScope.class, true, false);
-      	}
-
-      	public void registerACustomScopeContext(@Observes final AfterBeanDiscovery event) {
-      		event.addContext(new ACustomScopeContext());
-      	}
-      }
+    :::java    
+    public class ACustomScopeExtension implements Extension, Serializable {
+
+    	public void addACustomScope(@Observes final BeforeBeanDiscovery event) {
+    		event.addScope(ACustomScope.class, true, false);
+    	}
+
+    	public void registerACustomScopeContext(@Observes final AfterBeanDiscovery event) {
+    		event.addContext(new ACustomScopeContext());
+    	}
