 Besides, submariner now **do not** support the existence of multiple service CIDR or pod CIDR in a cluster.
 
 #### Data Plane:
 
 Submariner supports custom build handlers for different CNIs.

 ## How it works
 
 By using [Intel Multus CNI](https://github.com/intel/multus-cni), we can attach multiple network interfaces into a Kubernetes Pod.
-However, we still need some cluster-wide IPAM utilities to manage IP addresses for multi network to better mange other CNI plugins.
+However, we still need some cluster-wide IPAM utilities to manage IP addresses for multi network to better manage other CNI plugins.
 In Kube-OVN, we already have CRDs like Subnet and IP and functions for advanced IPAM like ip reservation, random allocation, static allocation and so on.
 We extend the Subnet to network providers other than ovn, so other CNI plugins can take use all the IPAM functions already exist in Kube-OVN.
