+# CPLD Update Daemon
+
+This daemon implements the update process for CPLD attached via I2C bus.
+
+## Configuration Example
+
+The following shows an example of entity manager configuration record for
+lattice LCMXO3LF-4300C CPLD.
+
+```json
+{
+  "Address": "0x40",
+  "Bus": 5,
+  "FirmwareInfo": {
+    "CompatibleHardware": "com.meta.Hardware.CPLD",
+    "VendorIANA": 40981
+  },
+  "Name": "LCMXO3LF_4300C",
+  "Type": "LatticeXO3Firmware"
+}
