To learn more about these APIs, see the AWS documentation for [importing snapshots](https://docs.aws.amazon.com/vm-import/latest/userguide/vmimport-import-snapshot.html) and [creating EBS-backed AMIs](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/creating-an-ami-ebs.html#creating-launching-ami-from-snapshot).
