Please note that as of late last year the official development environment is now built with Vagrant. The primary repo contains a Vagrantfile and all the chef recipes (derived from our production recipes where possible) necessary to configure a base Ubuntu box for LW development.

These days Vagrant is being superseded by Docker, I might have a go at turning the VagrantFile into a Dockerfile if anyone is interested.
