This project uses vagrant. To get up and running, install vagrant and VirtualBox.
Make sure the Vagrant binary is in your PATH. On *nix OSes the installer will take care of it, I'm not so sure about Windows.
Then, navigate to the project folder in your terminal, and type
vagrant up followed by vagrant provision. Then: vagrant ssh, and finally /vagrant/bin/www.
The project has port forwarding to localhost.
Simply fire up your browser and go to localhost:8080, or https://localhost:8443.
Be careful though, the SSL warning bites!
The default username is admin, the default password is (you guessd it) admin.
