-## Unix Domain Sockets
-
-The async client provides support for connecting through a unix domain socket via the `uds` parameter. This is useful when making requests to a server that is bound to a socket file rather than an IP address.
-
-Here's an example requesting the Docker Engine API:
-
-```python
-import httpx
-
-
-async with httpx.AsyncClient(uds="/var/run/docker.sock") as client:
-    # This request will connect through the socket file.
-    resp = await client.get("http://localhost/version")
-```
-
-This functionality is not currently available in the synchronous client.
