+# About NebulaGraph licenses
+
+## What NebulaGraph licenses do
+
+NebulaGraph licenses are the legal permissions granted by Vesoft Co., Ltd., allowing you to utilize the capabilities of a NebulaGraph Enterprise Edition database and its associated software. You can buy a NebulaGraph license on a cloud marketplace or by contacting Vesoft's sales team. Currently, the only cloud marketplace available is the AWS Marketplace. You can purchase a NebulaGraph license from [NebulaGraph Enterprise (by Node)](https://aws.amazon.com/marketplace/pp/prodview-kvpxjh5b4dfno) on the AWS Marketplace.
+
+After purchasing a NebulaGraph license, you must obtain a [license key](2.license-management-suite/2.license-center.md) by [binding an LMID through the LC](2.license-management-suite/2.license-center.md). Once the license key is obtained, you need to use the [LM](2.license-management-suite/3.license-manager.md) service to load the license key. When starting the NebulaGraph database and associated software, the LM service will check the validity of the license. If the license is valid, then the graph database and associated software will function normally. Otherwise, the graph database and associated software will not be functional.
+
+You can view the license information, including the expiration date, nodes purchased, and license key on the [LC](2.license-management-suite/2.license-center.md) or by using the [LM](2.license-management-suite/3.license-manager.md) client to query the license information via the command line.
