+#### This configuration file mounts an Amazon EFS file system to a directory named /efs. To mount
+#### the file system to a different path, modify the MOUNT_DIRECTORY value in the "option_settings"
+#### section.
+####
+#### The FILE_SYSTEM_ID setting references a resource named "FileSystem", which is created by the
+#### storage-efs-createfilesystem.config configuration file. To use this file to mount a
+#### file system that you created outside of AWS Elastic Beanstalk, replace the Ref with the
+#### resource ID (e.g., fs-e7605f4e):
+####
+####      FILE_SYSTEM_ID: fs-e7605f4e
+####
+#### If your environment and file system are in a custom VPC, you must configure the VPC to allow
+#### DNS resolution and DNS host names. See this topic in the VPC User Guide for more information:
+####    http://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/vpc-dns.html
