+// dear imgui: Renderer for WebGPU
+// This needs to be used along with a Platform Binding (e.g. GLFW)
+// (Please note that WebGPU is currently experimental, will not run on non-beta browsers, and may break.)
+
+// Important note to dawn and/or wgpu users: when targeting native platforms (i.e. NOT emscripten),
+// one of IMGUI_IMPL_WEBGPU_BACKEND_DAWN or IMGUI_IMPL_WEBGPU_BACKEND_WGPU must be provided.
+// Add #define to your imconfig.h file, or as a compilation flag in your build system.
+// This requirement will be removed once WebGPU stabilizes and backends converge on a unified interface.
+//#define IMGUI_IMPL_WEBGPU_BACKEND_DAWN
+//#define IMGUI_IMPL_WEBGPU_BACKEND_WGPU
+
+// Implemented features:
+//  [X] Renderer: User texture binding. Use 'WGPUTextureView' as ImTextureID. Read the FAQ about ImTextureID!
+//  [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
+//  [X] Renderer: Expose selected render state for draw callbacks to use. Access in '(ImGui_ImplXXXX_RenderState*)GetPlatformIO().Renderer_RenderState'.
+
+// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
+// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
