 # 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).
+The spine-glfw runtime provides functionality to load, manipulate and render [Spine](http://esotericsoftware.com) skeletal animation data using [GLFW](https://www.glfw.org/) and OpenGL. spine-glfw is based on [spine-c](../spine-c) and [spine-cpp](../spine-cpp). Note that spine-c depends on spine-cpp, so both are required regardless of which API you choose to use.

+## Usage
+
+### Integration with CMake (Recommended)
+
+The easiest way to integrate spine-glfw into your project is via CMake FetchContent:
+
+```cmake
+include(FetchContent)
+FetchContent_Declare(
+    spine-glfw
+    GIT_REPOSITORY https://github.com/esotericsoftware/spine-runtimes.git
+    GIT_TAG 4.3
+    SOURCE_SUBDIR spine-glfw
+)
+FetchContent_MakeAvailable(spine-glfw)
+
+# Link against spine-glfw (includes both C and C++ APIs)
+target_link_libraries(your_target spine-glfw)
+```
+
+This will automatically fetch and build spine-glfw along with its dependencies (spine-c, spine-cpp, GLFW, and glbinding).
+
+### Manual Integration
+
+If you prefer manual integration:
+
+1. Download the Spine Runtimes source using git (`git clone https://github.com/esotericsoftware/spine-runtimes`) or download it as a zip.
+2. Add the required source files to your project:
+   - Add sources from `spine-cpp/src`, `spine-c/src`, and `spine-glfw/src`
+3. Add the include directories: `spine-cpp/include`, `spine-c/include`, and `spine-glfw/src`
+4. Link against GLFW and OpenGL libraries
+
+See the [Spine Runtimes documentation](http://esotericsoftware.com/spine-documentation#runtimes) for detailed API usage.
+
+## Examples
+
+The repository includes example code for both C and C++ APIs:
+- C example: [example/main-c.cpp](example/main-c.cpp)
+- C++ example: [example/main.cpp](example/main.cpp)
+
+### Building the Examples
+
+The project includes a `build.sh` script for easy building:
+
+```bash
+cd spine-glfw
+./build.sh           # Build debug version
+./build.sh release   # Build release version
+./build.sh clean     # Clean and rebuild
+```
