 Lambda Linux VirtualBox flavor is a Linux guest ISO image for VirtualBox
 hypervisor. It is designed to provide a stable, secure and high performance
 local container host. It runs completely from RAM. Lambda Linux is based
-on [Amazon Linux](https://aws.amazon.com/amazon-linux-ami/), the Linux operating
-system that powers [AWS](https://aws.amazon.com/).
+on [Alpine Linux](https://alpinelinux.org/) user space and a customized minimal
+kernel

-### Container Flavor
-
-The Container flavor of Lambda Linux Base OS, used for development and testing
-is available
-on [Docker Hub](https://hub.docker.com/r/lambdalinux/baseimage-lambda).
-
-For your workloads on AWS we recommend
-using [baseimage-amzn](https://github.com/lambda-linux/baseimage-amzn)
