Development environment with Vagrant
The easiest way to hack on UDD is using the Vagrant development environment.
Just run vagrant up in the UDD source code. See Vagrantfile and the vagrant scripts for details.
This development environment supports setting up tunnels to access the main instance remotely, or dumping/importing data locally, depending on what you want to work on.
If you don't want to use Vagrant, your best bet is to look at the Vagrant provision script to understand how to setup your own instance manually.
