Thank you for the feedback, this makes sense!

I updated the example to include the imports:

```

import { init, tx, id } from "@instantdb/react";

const db = init({ appId: process.env.NEXT_PUBLIC_APP_ID, });

function Chat() {

  // 1. Read
  const { isLoading, error, data } = db.useQuery({
    messages: {},
  });

  // 2. Write
  const addMessage = (message) => {
    db.transact(tx.messages[id()].update(message));
  };

  // 3. Render!
  return <UI data={data} onAdd={addMessage} />;

}

```

What do you think?
