+This plugin provides two types of nodes:

+#### 1. MediaPlane Node (MPxNode with Viewport 2.0)
 
 ```mel
 // MEL command
 createNode MediaPlane;
 ```
 
+#### 2. MediaImagePlane Node (MPxImagePlane)
+
+```mel
+// Create MediaImagePlane node
+createNode mediaImagePlane;
+
+// Attach to camera (required for image plane)
+imagePlane -edit -camera "persp" <nodeName>;
+```

 ### Use AE Template
 
-The plugin includes a custom Attribute Editor template (AETemplateMediaPlane.mel). After installation, the MEL file is automatically placed in the Maya scripts directory and will be loaded when the plugin is loaded.
+The plugin includes custom Attribute Editor templates:
+- `AETemplateMediaPlane.mel` - For MediaPlane node
+- `AEMediaImagePlaneTemplate.mel` - For MediaImagePlane node
+
+After installation, the MEL files are automatically placed in the Maya scripts directory and will be loaded when the plugin is loaded.
 
 For manual loading in Script Editor:
 
 ```mel
-// Source the AE template
+// Source the AE template for MediaPlane
 source "AETemplateMediaPlane.mel";
+
+// Source the AE template for MediaImagePlane
+source "AEMediaImagePlaneTemplate.mel";

+| Viewport | Viewport 2.0 draw override | Native image plane |
+| Camera attachment | Not required | Required |
+| Use case | 3D plane in scene | Standard image plane |
+
+### MediaImagePlane Specific Usage
+
+The MediaImagePlane node integrates with Maya's native image plane system:
+
+```mel
+// Full workflow example
+createNode mediaImagePlane;
+rename "imagePlane1" "myVideoPlane";
+
+// Attach to camera
+imagePlane -edit -camera "persp" "myVideoPlane";

+// Description: 
+//   Demonstrates how to create your own custom image plane based on
+//   Maya's internal image plane classes. This allows API users to
+//   override the default Maya image plane behavior. This class works
+//   like typical API nodes in that it can have a compute method and
+//   can contain static attributes added by the API user.  This
+//   example class overrides the default image plane behavior and
+//   allows users to add transparency to an image plane using the
+//   transparency attribute on the node. Note, this code also 
+//   illustrates how to use MImage to control the floating point
+//   depth buffer.  When useDepthMap is set to true, depth is added
+//   is added to the image such that half of the image is at the near 
+//   clip plane and the remaining half is at the far clip plane. 
+//
+//   Note, once the image plane node has been created it you must
+//   attached it to the camera shape that is displaying the node.
+//   You need to use the imagePlane command to attach the image plane 
+//   you created to the specified camera.
+//
+//   This example works only with renderers that use node evaluation
+//   as a part of the rendering process, e.g. Maya Software. It does 
+//   not work with 3rd party renderers that rely on a scene translation 
+//   mechanism.
+// 
+//   For example, 
+//     string $imageP = `createNode customImagePlane`;
+//     imagePlane -edit -camera "persp" $imageP
