+iSulad is an OCI-compliant container runtime engine that emphasizes simplicity, robustness, performance and lightweight. 
 
-As a daemon process, it manages the entire container life cycle of the host system, including image transmission and storage, container execution and monitoring management, container resource management, and network management. iSulad provides Docker-like CLI man-machine interfaces for external systems.

 ## Subsystem
 
-You can interact with the iSulad by calling  gRPC APIs provided by the subsystem.

-- **image service** :   Image management service, which provides image-related operations, such as image download, query, and deletion. 
-- **execution service**:  Container life cycle management service, which provides container-related operations, such as container creation, startup, and deletion.

+- **execution service**:  Container life cycle management service, provides container-related operations, such as container creation, startup, and deletion. 
 - **network**：The network subsystem is responsible for network management capabilities of the pod of the CRI. When a pod is started, the pod is added to the network plane specified in the configuration file through the CNI interface. When a pod is stopped, the CNI API is used to remove the pod from the network plane where the pod is located and clear related network resources.
