 Installation
 ------------
 
-Aquameta is designed for installation on a Ubuntu 18.04 instance.  Aquameta installs a number of `apt` packages.  It works best on a clean install of Ubuntu.  We recommend using a KVM instance, or Amazon EC2 instance.
+Aquameta is most easily installed on a Ubuntu 18.04 instance; its installer manages dependencies by as `apt` packages.
+
+First, setup a clean Ubuntu 18.04 instance.  You can run on bare metal, or using a virtual machine such as [VirtualBox](https://linuxhint.com/install_ubuntu_18-04_virtualbox/) on Mac OSX and Windows, or [KVM](https://linuxconfig.org/install-and-set-up-kvm-on-ubuntu-18-04-bionic-beaver-linux) on a Linux machine.
+
+Once you have an Ubuntu machine setup, installation is very easy:
 
 1. `git clone https://github.com/aquametalabs/aquameta.git`
 2. `cd aquameta`
