 Functionality between the synchronous and asynchronous clients is otherwise identical.
 
+### With aiohttp
+
+By default, the async client uses `httpx` for HTTP requests. However, for improved concurrency performance you may also use `aiohttp` as the HTTP backend.
+
+You can enable this by installing `aiohttp`:
+
+```sh
+# install from PyPI
+pip install finch-api[aiohttp]
+```
+
+Then you can enable it by instantiating the client with `http_client=DefaultAioHttpClient()`:
+
+```python
+import asyncio
+from finch import DefaultAioHttpClient
+from finch import AsyncFinch
+
+
+async def main() -> None:
+    async with AsyncFinch(
+        access_token="My Access Token",
+        http_client=DefaultAioHttpClient(),
+    ) as client:
+        page = await client.hris.directory.list()
+        print(page.individuals)
+
+
+asyncio.run(main())
+```
+
 ## Using types
 
 Nested request parameters are [TypedDicts](https://docs.python.org/3/library/typing.html#typing.TypedDict). Responses are [Pydantic models](https://docs.pydantic.dev) which also provide helper methods for things like:
