+If you're going to use `Relay` and `SimplePool` you must also import `nostr-tools/relay-wasm` and/or `nostr-tools/pool-wasm` instead of the defaults:
+
+```js
+import Relay, { Subscription } from 'nostr-tools/relay-wasm'
+import SimplePool from 'nostr-tools/pool-wasm'
+```
+
 This may be faster than the pure-JS [noble libraries](https://paulmillr.com/noble/) used by default and in `nostr-tools/pure`.
