+    The LM service is only used to manage the NebulaGraph Enterprise license. If you are using the Community Edition of NebulaGraph, you do not need to deploy LM.
 
 Before deploying NebulaGraph Enterprise 3.5.0 or later using Operator, you first need to deploy [License Manager (LM)](../../9.about-license/2.license-management-suite/3.license-manager.md) and configure the NebulaGraph Enterprise [License](../../9.about-license/1.license-overview.md) in LM. LM is a standalone service used to manage the NebulaGraph license. LM checks the validity of the license when NebulaGraph Enterprise database starts. If the License is invalid, the database will not be able to start.
