+Description
+===========
+
+This folder contains resources for building a simple demo decompressing and rendering Draco within Unity.
+
+If you are looking for more information on using Draco within Unity, this site [https://gitlab.com/atteneder/DracoUnity](https://gitlab.com/atteneder/DracoUnity) is a much better resource. There are more samples as well as support for more platforms.
+
+In this folder we currently support two types of usages:
+* Import Draco compressed mesh as assets during design time.
+* Load/decode Draco files in runtime.
+
+Prerequisite
+============
+
+To start, you need to have the Draco unity plugin. You can either use the
+prebuilt libraries provided in this folder or build from source.
+Note that the plugin library for different platforms has different file extension.
+
+| Platform | Library name |
+| -------- | ------------ |
+| Mac OS | dracodec_unity.bundle |
+| Android | libdracodec_unity.so |
+| Windows | dracodec_unity.dll |
+
+Prebuilt Library
+----------------
+
+We have built library for several platforms:
+
+| Platform | Tested Environment |
+| -------- | ------------------ |
+| .bundle  | macOS Sierra + Xcode 8.3.3 |
+| armeabi-v7a(.so) | Android 8.1.0 |
+| .dll | Win10 + Visual Studio 2017 |
+
+Build From Source
+-----------------
+See [BUILDING.md](BUILDING.md) for information on building Draco Unity plug-ins from source.
+
+Create Draco Demo Unity Project
+===============================
+
+Create a new 3D project in Unity.
+
+Copy Library to Your Project
+----------------------------
+Copy the plugin library to your Unity project in `Assets/Plugins/`.
+For Android Arm7:
+
+~~~~ bash
+cp path/to/your/libdracodec_unity.so path/to/your/Unity/Project/Assets/Plugins/Android/libs/armeabi-v7a/
+~~~~
+
+For Android Arm8:
+
+~~~~ bash
+cp path/to/your/libdracodec_unity.so path/to/your/Unity/Project/Assets/Plugins/Android/libs/arm64-v8a/
+~~~~
+
+For Mac:
+
+~~~~ bash
+cp path/to/your/dracodec_unity.bundle path/to/your/Unity/Project/Assets/Plugins/
+~~~~
+
+For Win:
+
+~~~~ bash
+cp path/to/your/dracodec_unity.dll path/to/your/Unity/Project/Assets/Plugins/
+~~~~
+
+
+Copy Unity Scripts to Your Project
+----------------------------------
+
+~~~~ bash
+cp unity/DracoDecodingObject.cs path/to/your/Unity/Project/Assets/
+cp unity/DracoMeshLoader.cs path/to/your/Unity/Project/Assets/
+~~~~
+
+Player Settings Change
+-------------------------------
+Open player settings. Make sure `Allow unsafe code` is checked, so Unity can load our plug-ins.
+
+Copy Draco Mesh to Your Project
+-------------------------------
+Because Unity can only recognize file extensions known to Unity, you need to change your compressed .drc file to .drc.bytes so that Unity will recognize it as a binary file. For example, if you have file `bunny.drc` then change the file name to `bunny.drc.bytes`.
+
+~~~~ bash
+cp path/to/your/bunny.drc path/to/your/Unity/Project/Assets/Resources/bunny.drc.bytes
+~~~~
+
+
+---
+
+Load Draco Assets in Runtime
+============================
+For example, please see [DracoDecodingObject.cs](DracoDecodingObject.cs) for usage. To start, you can create an empty GameObject and attach this script to it. [DracoDecodingObject.cs](DracoDecodingObject.cs) will load `bunny.drc.bytes` by default.
+
+Enable Library in Script Debugging
+----------------------------------
+If you have library for the platform you are working on, e.g. `dracodec_unity.bundle` for Mac or `dracodec_unity.dll` for  Windows. You should be able to use the plugin in debugging mode.
+
+---
+
+Import Compressed Draco Assets
+==============================
+In this section we will describe how to import Draco files (.drc) to Unity as
+other 3D formats at design time, e.g. obj, fbx.
+Note that importing Draco files doesn't mean the Unity project will export models as Draco files.
+
+Copy [DracoFileImporter.cs](Editor/DracoFileImporter.cs) which enables loading (This file is only used for import Draco files):
+
+~~~~ bash
+cp DracoFileImporter.cs path/to/your/Unity/Project/Assets/Editor/
+~~~~
+
+If you have followed the previous steps, you just need to copy your asset, e.g. `bunny.drc.bytes`, to `Your/Unity/Project/Assets/Resources`, the project will automatically load the file and add the models to the project.

+## GLTFUtility
+Allows you to import and export glTF files during runtime and in editor.
+glTF is a new opensource 3d model transmission format which supports everything you'll ever need from a format in Unity.
+[Read more about glTF here](https://www.khronos.org/gltf/)

+### Known issues
+* `ArgumentNullException: Value cannot be null` in build but not in editor.
+  * This is most likely due to shaders being stripped from the build. To fix this, add the GLTFUtility shaders to the Always Included Shaders list in Graphic Settings.
+* Draco compression does not work on iOS and UWP
+  * More info on [#133](https://github.com/Siccity/GLTFUtility/issues/133)
+
+### Runtime import API
+```cs
+// Single thread
+using Siccity.GLTFUtility;
+
+void ImportGLTF(string filepath) {
+   GameObject result = Importer.LoadFromFile(filepath);
+}
+```
+```cs
+// Multithreaded
+using Siccity.GLTFUtility;
+
+void ImportGLTFAsync(string filepath) {
+   Importer.ImportGLTFAsync(filepath, new ImportSettings(), OnFinishAsync);
+}
+
+void OnFinishAsync(GameObject result, AnimationClip[] animations) {
+   Debug.Log("Finished importing " + result.name);
+}
+```
+
+### Important shader note
+To ensure that Unity includes the GLTFUtility shaders in builds, you must add these shaders to the 'Always Included Shaders' list.
+
+1. Open Edit -> Project Settings
+2. Open Graphics
+3. Scroll to Always Included Shaders
+4. Under Size, increase the value by 4 and hit Enter.
+5. In the Project panel, navigate to Packages/GLTFUtility/Materials/Built-in.
+6. In this directory are 4 .shader files.
+7. Drag and drop each of the 4 files into one of the 4 newly created rows in Always Included Shaders.
