If your application uses a [Content Security Policy](https://developer.mozilla.org/en-US/docs/Web/HTTP/Guides/CSP), then this requires:
 
 - `connect-src` to allow `https://opencor.ws` (which is needed for the threaded WASM file anyway); and
 - `script-src` and `worker-src` to allow `blob:`.
 
-If you would rather not allow `blob:` (or would rather not fetch `libopencor.js` from `https://opencor.ws`), then you can self-host `libopencor.js` by downloading it from `https://opencor.ws/libopencor/downloads/wasm/<version>/libopencor.js` and serving it, as a JavaScript file, from the above URL. Make sure to do this again whenever you update the `@opencor/opencor` package, since `<version>` will then change.
