+### SharedArrayBuffer Errors
+
+This project uses SharedArrayBuffer to manage threading. Currently most browsers will only enable SharedArrayBuffer when the following headers are sent along side the JavaScript/WASM:
+```
+Cross-Origin-Opener-Policy: same-origin
+Cross-Origin-Embedder-Policy: require-corp
+```
