-When installed, the PTP Operator searches your cluster for Precision Time Protocol (PTP) capable network devices on each node. It creates and updates a `NodePtpDevice` custom resource (CR) object for each node that provides a compatible PTP-capable network device.
+When installed, the PTP Operator searches your cluster for Precision Time Protocol (PTP) capable network devices on each node. The Operator creates and updates a `NodePtpDevice` custom resource (CR) object for each node that provides a compatible PTP-capable network device.
+
+Network interface controller (NIC) hardware with built-in PTP capabilities sometimes require a device-specific configuration. You can use hardware-specific NIC features for supported hardware with the PTP Operator by configuring a plugin in the `PtpConfig` custom resource (CR). The `linuxptp-daemon` service uses the named parameters in the `plugin` stanza to start `linuxptp` processes, `ptp4l` and `phc2sys`, based on the specific hardware configuration.

+[IMPORTANT]
+====
+In {product-title} {product-version}, the Intel E810 NIC is supported with a `PtpConfig` plugin.
