+# Wukong: Simplified Management of ONVIF IP Devices
+
+Wukong is a robust implementation of the ONVIF protocol designed for the efficient management of ONVIF-compliant IP devices, including cameras. This project aims to provide a user-friendly and streamlined solution for the convenient management of IP cameras and other devices that adhere to the ONVIF standard.
+
+With Wukong, users can easily configure, monitor, and control their ONVIF devices, enhancing the overall experience of managing surveillance systems and ensuring seamless integration within various environments.
+
+## Requirements
+
+- Zabbix agent 2 version 6.0.0 or newer
+- Go programming language version 1.20 or newer (required only for building the plugin from the source)
+
+## Installation
+
+The plugin can be compiled using `go build`.
