 In async apps, all middleware/listeners must be async functions. When calling utility methods (like `ack` and `say`) within these functions, it's required to use the `await` keyword.

 # Using async (asyncio)
 
-To use the async version of Bolt, you can import and initialize an `AsyncApp` instance (rather than `App`). `AsyncApp` relies on [AIOHTTP](https://docs.aiohttp.org) to make API requests, which means you'll need to install `aiohttp` (by adding to `requirements.txt` or running `pip install aiohttp`).

 Sample async projects can be found within the repository's [examples](https://github.com/slackapi/bolt-python/tree/main/examples) folder.

-非同期バージョンの Bolt を使用する場合は、`App` の代わりに `AsyncApp` インスタンスをインポートして初期化します。`AsyncApp` では [AIOHTTP](https://docs.aiohttp.org/) を使って API リクエストを行うため、`aiohttp` をインストールする必要があります（`requirements.txt` に追記するか、`pip install aiohttp` を実行します）。
