This is a VM image that has all of the dependencies you need for class installed. Once you have cloned this repository you can get to the VM by running the following:

vagrant up # This will create and provision the VM if not already done.
vagrant ssh # This will log you into the VM

You can subsequently suspend the VM using vagrant suspend and halt the VM either by running sudo shutdown -h now inside the VM or calling vagrant halt on the outside.

Finally you can delete the VM by calling vagrant destroy, however note that this will delete all content in the VM and is probably not what you want to do.
