 ## Networking requirements
 
 To enable the Azure Disk Encryption feature, the Linux VMs must meet the following network endpoint configuration requirements:
+
   - To get a token to connect to your key vault, the Linux VM must be able to connect to an Azure Active Directory endpoint, \[login.microsoftonline.com\].
   - To write the encryption keys to your key vault, the Linux VM must be able to connect to the key vault endpoint.
   - The Linux VM must be able to connect to an Azure storage endpoint that hosts the Azure extension repository and an Azure storage account that hosts the VHD files.
