 ### Usage
 
-**The core of Dear ImGui is self-contained within a few platform-agnostic files** which you can easily compile in your application/engine. They are all the files in the root folder of the repository (imgui*.cpp, imgui*.h). **No specific build process is required**. You can add the .cpp files into your existing project.

They are all the files in the root folder of the repository (`imgui*.cpp`, `imgui*.h`). **No specific build process is required**: you can add all files into your existing project.
 
 **Backends for a variety of graphics API and rendering platforms** are provided in the [backends/](https://github.com/ocornut/imgui/tree/master/backends) folder, along with example applications in the [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder. You may also create your own backend. Anywhere where you can render textured triangles, you can render Dear ImGui.
 
+C++20 users wishing to use a module may the use [stripe2933/imgui-module](https://github.com/stripe2933/imgui-module) third-party extension.
+
 See the [Getting Started & Integration](#getting-started--integration) section of this document for more details.
 
 After Dear ImGui is set up in your application, you can use it from \_anywhere\_ in your program loop:

 iOS to fix shader compatibility. (#9076)

Edit original PR to keep metallib shader binary since next commit is going to use them.

+//  2025-11-26: Use MSL shaders on macOS to support macOS 10.14+ (instead of Metallib shaders requiring macOS 14+). Requires calling SDL_CreateGPUDevice() with SDL_GPU_SHADERFORMAT_MSL.
 //  2025-09-18: Call platform_io.ClearRendererHandlers() on shutdown.
 //  2025-08-20: Added ImGui_ImplSDLGPU3_InitInfo::SwapchainComposition and ImGui_ImplSDLGPU3_InitInfo::PresentMode to configure how secondary viewports are created.
 //  2025-08-08: *BREAKING* Changed ImTextureID type from SDL_GPUTextureSamplerBinding* to SDL_GPUTexture*, which is more natural and easier for user to manage. If you need to change the current sampler, you can access the ImGui_ImplSDLGPU3_RenderState struct. (#8866, #8163, #7998, #7988)
