+**glTF loader and writer**
+(**Single-file/stb-style C glTF loader and writer**)
+
+Used in: [bgfx](https://github.com/bkaradzic/bgfx), [Filament](https://github.com/google/filament), [gltfpack](https://github.com/zeux/meshoptimizer/tree/master/gltf), [raylib](https://github.com/raysan5/raylib), [Unigine](https://developer.unigine.com/en/docs/2.14.1/third_party?rlang=cpp#cgltf), and more!
+
+## Usage: Loading
+Loading from file:
+```odin
+package main
+
+import "vendor:cgltf"
+
+main :: proc() {
+	options: cgltf.options
+	data, result := cgltf.parse_file(&options, "scene.gltf")
+	if result != .success {
+		/* TODO handle error */
+	}
+	defer cgltf.free(data)
+	/* TODO make awesome stuff */
+}
+```
+
+Loading from memory:
+```odin
+package main
+
+import "vendor:cgltf"
+
+main :: proc() {
+	buf: []byte = ... // data to glb or gltf file data
+
+	options: cgltf.options
+	data, result := cgltf.parse(&options, raw_data(buf), len(buf))
+	if result != .success {
+		/* TODO handle error */
+	}
+	defer cgltf.free(data)
+	/* TODO make awesome stuff */
+}
+```
+
+
+Note that cgltf does not load the contents of extra files such as buffers or images into memory by default. You'll need to read these files yourself using URIs from `data.buffers[]` or `data.images[]` respectively.
+For buffer data, you can alternatively call `cgltf.load_buffers`, which will use `^clib.FILE` APIs to open and read buffer files. This automatically decodes base64 data URIs in buffers. For data URIs in images, you will need to use `cgltf.load_buffer_base64`.
+
+**For more in-depth documentation and a description of the public interface refer to the top of the `cgltf.h` file.**
+
+## Usage: Writing
+When writing glTF data, you need a valid `cgltf.data` structure that represents a valid glTF document. You can construct such a structure yourself or load it using the loader functions described above. The writer functions do not deallocate any memory. So, you either have to do it manually or call `cgltf.free()` if you got the data by loading it from a glTF document.
+
+Writing to file:
+```odin
+package main
+
+import "vendor:cgltf"
+
+main :: proc() {
+	options: cgltf.options
+	data: ^cgltf.data = /* TODO must be valid data */
+	result := cgltf.write_file(&options, "out.gltf", data)
+	if result != .success {
+		/* TODO handle error */
+	}
+}
+```
+
+Writing to memory:
+```c
+package main
+
+import "vendor:cgltf"
+
+main :: proc() {
+	options: cgltf.options
+	data: ^cgltf.data = /* TODO must be valid data */
+
+	size := cgltf.write(&options, nil, 0, data)
+
+	buf := make([]byte, size)
+
+	written := cgltf.write(&options, raw_data(buf), size, data)
+	if written != size {
+		/* TODO handle error */
+	}
+}
+```
+
+Note that cgltf does not write the contents of extra files such as buffers or images. You'll need to write this data yourself.
+
+**For more in-depth documentation and a description of the public interface refer to the top of the `cgltf_write.h` file.**

+
+## Features
+cgltf supports core glTF 2.0:
+- glb (binary files) and gltf (JSON files)
+- meshes (including accessors, buffer views, buffers)
+- materials (including textures, samplers, images)
+- scenes and nodes
+- skins
+- animations
+- cameras
+- morph targets
+- extras data
+
+cgltf also supports some glTF extensions:
+- EXT_mesh_gpu_instancing
+- EXT_meshopt_compression
+- KHR_draco_mesh_compression (requires a library like [Google's Draco](https://github.com/google/draco) for decompression though)
+- KHR_lights_punctual
+- KHR_materials_clearcoat
+- KHR_materials_emissive_strength
+- KHR_materials_ior
+- KHR_materials_iridescence
+- KHR_materials_pbrSpecularGlossiness
+- KHR_materials_sheen
+- KHR_materials_specular
+- KHR_materials_transmission
+- KHR_materials_unlit
+- KHR_materials_variants
+- KHR_materials_volume
+- KHR_texture_basisu (requires a library like [Binomial Basisu](https://github.com/BinomialLLC/basis_universal) for transcoding to native compressed texture)
+- KHR_texture_transform
+
+cgltf does **not** yet support unlisted extensions. However, unlisted extensions can be accessed via "extensions" member on objects.
+
+## Contributing
+Everyone is welcome to contribute to the library. If you find any problems, you can submit them using [GitHub's issue system](https://github.com/jkuhlmann/cgltf/issues). If you want to contribute code, you should fork the project and then send a pull request.
+
+
+## Dependencies
+None.
+
+C headers being used by the implementation:
+```
+#include <stddef.h>
+#include <stdint.h>
+#include <string.h>
+#include <stdlib.h>
+#include <stdio.h>
+#include <limits.h>
+#include <assert.h> // If asserts are enabled.
+```
+
+Note, this library has a copy of the [JSMN JSON parser](https://github.com/zserge/jsmn) embedded in its source.
