+# spine-glfw
+
+The spine-glfw runtime provides basic functionality to load and manipulate [spine](http://esotericsoftware.com) skeletal animation data using C or C++ and render them via [GLFW](https://www.glfw.org/) and [glbinding](https://github.com/cginternals/glbinding).
+
+## Licensing
+
+You are welcome to evaluate the Spine Runtimes and the examples we provide in this repository free of charge.
+
+You can integrate the Spine Runtimes into your software free of charge, but users of your software must have their own [Spine license](https://esotericsoftware.com/spine-purchase). Please make your users aware of this requirement! This option is often chosen by those making development tools, such as an SDK, game toolkit, or software library.
+
+In order to distribute your software containing the Spine Runtimes to others that don't have a Spine license, you need a [Spine license](https://esotericsoftware.com/spine-purchase) at the time of integration. Then you can distribute your software containing the Spine Runtimes however you like, provided others don't modify it or use it to create new software. If others want to do that, they'll need their own Spine license.
+
+For the official legal terms governing the Spine Runtimes, please read the [Spine Runtimes License Agreement](http://esotericsoftware.com/spine-runtimes-license) and Section 2 of the [Spine Editor License Agreement](http://esotericsoftware.com/spine-editor-license#s2).
+
+## Spine version
+
+spine-cpp works with data exported from spine 4.2.xx.
+
+spine-cpp supports all spine features, except two color tinting.
