+# Babylon.js glTF File Loader
+
+# Usage
+The glTF file loader is a SceneLoader plugin.
+Just reference the loader in your HTML file:
+
+```
+<script src="babylon.2.1.js"></script>
+<script src="babylon.glTFFileLoader.js"></script>
+```
+
+And then, call the scene loader:
+```
+BABYLON.SceneLoader.Load("./", "duck.gltf", engine, function (scene) { 
+   // do somethings with the scene
+});
+```
+
+## Supported features
+* Load scenes (SceneLoader.Load)
+* Import geometries
+    * From binary files
+    * From base64 buffers
+* Import lights
+* Import cameras
+* Import and set custom shaders (if no shaders, the Babylon.js default material is applied)
+    * Automatically bind attributes
+    * Automatically bind matrices
+    * Set uniforms
+* Import and set animations
+
+## Unsupported features
+* ImportMesh function
+* Skinning
+    * Skeletons
+    * Bones
+    * Hardware skinning (shaders support)
+* Shaders
+    * Set uniforms with types MAT2 and MAT3
+* Handle dummy nodes (empty nodes)
+
+## To improve
+* Y is UP
+* Test on more animations
