-# Vagrant
-
-The simplest way to get pokecrystal to compile is to use Vagrant and
-VirtualBox. Follow these steps:
-
-* [Download and install Vagrant](http://www.vagrantup.com/downloads.html)
-* Follow the instructions to [download and install VirtualBox](http://docs-v1.vagrantup.com/v1/docs/getting-started/)
-* Run these commands:
-
-```bash
-vagrant box add pokecrystal http://diyhpl.us/~bryan/irc/pokecrystal/pokecrystal.box
-mkdir vagrantbox
-cd vagrantbox
-vagrant init pokecrystal
-vagrant up
-vagrant ssh -c "cd /vagrant && git clone --recursive https://github.com/pret/pokecrystal"
-vagrant ssh
-```
-
-Running "vagrant ssh" will give you a shell to type commands into for compiling
-the source code. Then the "virtualbox" directory on the host appears as a shared
-folder inside of the guest virtual machine at "/vagrant".
-
-To build the project, run these commands in the guest (that is, inside "vagrant
-ssh"):
-
-```bash
-cd /vagrant/pokecrystal
-make
