 For your convenience, a forward declaration header is also provided, and can be included with `#include "lib_webgpu_fwd.h"`.
 
+# Using WebGPU via Dawn
+
+It is also possible to target WebGPU outside the browser via Dawn. When doing so, also compile the dawn-specific file with your project:
+
+ - [lib/lib_webgpu_dawn.cpp](https://github.com/juj/wasm_webgpu/blob/main/lib/lib_webgpu_dawn.cpp)
+
+TODO: add more instructions about targeting Dawn natively.

 ## Implementation Status
 
 The repository was last updated to be up to date with the WebGPU specification as of 🗓 **18th of November 2022**.
