+## POSIX and NFSv4 ACLs
+
+CSI PowerStore driver version 2.2.0 and later allows users to set user-defined permissions on NFS target mount directory using POSIX mode bits or NFSv4 ACLs.
+
+NFSv4 ACLs are supported for NFSv4 shares on NFSv4 enabled NAS servers only. Please ensure the order when providing the NFSv4 ACLs.
+
+To use this feature, provide permissions in `nfsAcls` parameter in values.yaml, secrets or NFS storage class.
+
+For example:
+
+1. POSIX mode bits
+
+```yaml
+nfsAcls: "0755"
+```
+
+2. NFSv4 ACLs
+
+```yaml
+nfsAcls: "A::OWNER@:rwatTnNcCy,A::GROUP@:rxtncy,A::EVERYONE@:rxtncy,A::user@domain.com:rxtncy"
+```
+
+>Note: If no values are specified, default value of "0777" will be set.
