What to install before the workshop
If your computer has at least 10 GB of hard disk space free and at least 3 GB of RAM, it's recommended to download and install the following:
Install VirtualBox: https://www.virtualbox.org/wiki/Downloads
and Vagrant: http://downloads.vagrantup.com/
This allows you to use a virtual machine at the workshop that already has everything set up. Otherwise, you'll need to perform a manual installation. The manual installation guide can be found here: https://wiki.openmrs.org/display/docs/Getting+Started+as+a+Developer, but will be covered in more depth at the workshop.
