+# 🆕 Add User Group
+
+If a user with capabilities such as AddMember, AddSelf, etc. has control, this module can add or remove users from the target group.
+
+### Add User to Group
+
+Only need to specify target user and target group name.
+
+
+```bash
+nxc smb <ip> -u user -p pass -M add-group -o USER=TargetUser Group=TargetGroup
+```
+
+If want to remove the target user to group, just need to specify REMOVE true value.

+nxc smb <ip> -u user -p pass -M add-group -o USER=TargetUser Group=TargetGroup REMOVE=True
+```
