 [Container Device Interface
 (CDI)](https://github.com/cncf-tags/container-device-interface/blob/main/SPEC.md)
 is a standardized mechanism for container runtimes to create containers which
 are able to interact with third party devices.
 
+CDI is currently only supported for Linux containers and is enabled by default
+since Docker Engine 28.3.0.
+
 With CDI, device configurations are declaratively defined using a JSON or YAML
 file. In addition to enabling the container to interact with the device node,
 it also lets you specify additional configuration for the device, such as

 Container Device Interface (CDI) is a
 [standardized](https://github.com/cncf-tags/container-device-interface/blob/main/SPEC.md)
 mechanism for container runtimes to create containers which are able to
 interact with third party devices.

 The Docker daemon supports running containers with CDI devices if the requested
 device specifications are available on the filesystem of the daemon.

+The default specification directories are:
 
 - `/etc/cdi/` for static CDI Specs
 - `/var/run/cdi` for generated CDI Specs
 
-Alternatively, you can set custom locations for CDI specifications using the

+To set custom locations for CDI specifications, use the
 `cdi-spec-dirs` option in the `daemon.json` configuration file, or the
-`--cdi-spec-dir` flag for the `dockerd` CLI.
+`--cdi-spec-dir` flag for the `dockerd` CLI:
