+## Development
+This project relies on a webgpu native implementation called dawn. If you plan
+on doing any development in this project you should install it systemwide to
+reduce the chances of having to re-install it while working on the project.
+I like to use this command to generate the build project so it has debug headers
+and is a shared library for faster linking `cmake -S . -B out/Debug -G Ninja

+-DCMAKE_BUILD_TYPE=Debug -DDAWN_BUILD_MONOLITHIC_LIBRARY=SHARED
+-DDAWN_BUILD_SAMPLES=OFF` and use the rest of the instructions
