+
+    You can choose a license key type based on your LM accessibility. 
+
+    - If your LM is accessible from the internet, you can select either **Online** or **Offline** mode. The **Online** mode is recommended, as it generates an online license key.
+    - If your LM is not accessible from the internet, then **Offline** mode is the only option available for generating an offline license key, as it can't reach out to the license server to validate the key itself.
 
 For information about how to bind the ID of your LM, see the following section **Bind LMID**.
