   ## Usage
 
   DraggableTreeView is organized by a custom adapter called TreeViewAdapter, I included a Simple implementation of the adapter class called SimpleTreeViewAdapter. 
-
+
+```java
       DraggableTreeView draggableTreeView = (DraggableTreeView)findViewById(R.id.dtv);
       TreeNode root = new TreeNode(this);
       TreeNode item = new TreeNode("Item 1");

       root.addChild(item);
       SimpleTreeViewAdapter adapter = new SimpleTreeViewAdapter(this,root);
       draggableTreeView.setAdapter(adapter);
+```
 
 You can also change both the succesful placeholder as well as the bad placeholder by passing a view through the function 
-
+
+```java
       adapter.setBadPlaceholder(view);
-      
+```
 or
+```java
+      adapter.setPlaceholder(view);      
+```
 
-      adapter.setPlaceholder(view);
-      
 By assigning the variable maxLevel a value you can define how many levels the tree view can drag to.
-
-      draggableTreeView.maxLevels = 4;
-
+```java
+      draggableTreeView.maxLevels = 4;     
+```
