 `TinyGLTF` is a header only C++11 glTF 2.0 https://github.com/KhronosGroup/glTF library.
 
-`TinyGLTF` uses Niels Lohmann's json library (https://github.com/nlohmann/json), so now it requires C++11 compiler.
-(Also, you can use RadpidJSON as an JSON backend)
-If you are looking for old, C++03 version, please use `devel-picojson` branch (but not maintained anymore).

 ## Status
 
-Currently TinyGLTF is stable and maintenance mode. No drastic changes and feature additions planned.
-
- - v2.8.0 Add URICallbacks for custom URI handling in Buffer and Image. PR#397
- - v2.7.0 Change WriteImageDataFunction user callback function signature. PR#393
- - v2.6.0 Support serializing sparse accessor(Thanks to @fynv).
- - v2.5.0 Add SetPreserveImageChannels() option to load image data as is.
- - v2.4.0 Experimental RapidJSON support. Experimental C++14 support(C++14 may give better performance)
- - v2.3.0 Modified Material representation according to glTF 2.0 schema(and introduced TextureInfo class)
- - v2.2.0 release(Support loading 16bit PNG. Sparse accessor support)
- - v2.1.0 release(Draco decoding support)
- - v2.0.0 release(22 Aug, 2018)!
-
-### Branches
-
-* `sajson` : Use sajson to parse JSON. Parsing only but faster compile time(2x reduction compared to json.hpp and RapidJson), but not well maintained.
+v2.0.0 release(22 Aug, 2018)!

-## Note on extension property
-
-In extension(`ExtensionMap`), JSON number value is parsed as int or float(number) and stored as `tinygltf::Value` object. If you want a floating point value from `tinygltf::Value`, use `GetNumberAsDouble()` method.
-
-`IsNumber()` returns true if the underlying value is an int value or a floating point value.
 
 ## Examples
 
 * [glview](examples/glview) : Simple glTF geometry viewer.
 * [validator](examples/validator) : Simple glTF validator with JSON schema.
-* [basic](examples/basic) : Basic glTF viewer with texturing support.
-* [build-gltf](examples/build-gltf) : Build simple glTF scene from a scratch.

-### WASI/WASM build

-Users who want to run TinyGLTF securely and safely(e.g. need to handle malcious glTF file to serve online glTF conver),
-I recommend to build TinyGLTF for WASM target.

 * `TINYGLTF_NOEXCEPTION` : Disable C++ exception in JSON parsing. You can use `-fno-exceptions` or by defining the symbol `JSON_NOEXCEPTION` and `TINYGLTF_NOEXCEPTION`  to fully remove C++ exception codes when compiling TinyGLTF.

-* `TINYGLTF_ENABLE_DRACO`: Enable Draco compression. User must provide include path and link correspnding libraries in your project file.
-* `TINYGLTF_NO_INCLUDE_JSON `: Disable including `json.hpp` from within `tiny_gltf.h` because it has been already included before or you want to include it using custom path before including `tiny_gltf.h`.

-
-You can add tinygltf using `add_subdirectory` feature.
-If you add tinygltf to your project using `add_subdirectory`, it would be better to set `TINYGLTF_HEADER_ONLY` on(just add an include path to tinygltf) and `TINYGLTF_INSTALL` off(Which does not install tinygltf files).

-# DirectX glTF Viewer
-
-## Overview
-
-This project was motivated by a lack of sample code demonstrating the graphics API agnostic nature of the glTF specification. The sample code is written using modern C++ and DirectX 12 for the client application.
-
-## Features
-
-* [x] DirectX 12
-* [ ] Loader
-* [ ] Animation
-* [ ] Morph Target
-* [ ] Physical Base Rendering
-* [ ] Environment Map
-
-## Dependencies
-
-* [CMake](https://github.com/Kitware/CMake)
-* [Vcpkg](https://github.com/Microsoft/vcpkg)
-* [GLFW](https://github.com/glfw/glfw)
-* [spdlog](https://github.com/gabime/spdlog)
-
-## Building
-
-### Install dependencies
-
-```
-vcpkg install glfw3:x64-windows
-vcpkg install spdlog:x64-windows
-```
-
-### Generate Project Files
-
-```
-mkdir build
-cmake . -B build -DCMAKE_TOOLCHAIN_FILE=${VCPKG_DIR}/script/buildsystem/vcpkg.cmake

-# Fuzzing test
-
-Do fuzzing test for TinyGLTF API.
-
-## Supported API
-
-* [x] LoadASCIIFromMemory
-* [ ] LoadBinaryFromMemory
-
-## Requirements
-
-* meson
-* clang with fuzzer support(`-fsanitize=fuzzer`. at least clang 8.0 should work)
-
-## Setup
-
-### Ubuntu 18.04
-
-```
-$ sudo apt install clang++-8
-$ sudo apt install libfuzzer-8-dev
-```
-
-Optionally, if you didn't set `update-alternatives` you can set `clang++` to point to `clang++8`
-
-```
-$ sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-8 10
-$ sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-8 10
