+[compiled]: https://rustwasm.github.io/wasm-bindgen/exbuild/webxr/
+[dox]: https://rustwasm.github.io/docs/wasm-bindgen/examples/webxr.html
+
+You can build the example locally with:
+
+```
+# Note: Requires unstable flag whilst WebXR in development
+$ RUSTFLAGS=--cfg=web_sys_unstable_apis npm run serve
+```
+
+and then visiting http://localhost:8080 in a browser should run the example!
