 To build, you need to have zig master (you can use [zvm](https://www.zvm.app/) to help you with this). Then just `zig build run` and that should be it!
 
+To build for wasm, use `zig build -Dtarget=wasm32-emscripten run`
+
 Note that if you change shaders, you have to recompile them manually - run compile_shaders.bat.
