+
+## Obtaining required software
+
+If you are starting this tutorial at the Fall 2017 P4 Developer Day, then we've already
+provided you with a virtual machine that has all of the required
+software installed.
+
+Otherwise, to complete the exercises, you will need to either build a
+virtual machine or install several dependencies.
+
+To build the virtual machine:
+- Install [Vagrant](https://vagrantup.com) and [VirtualBox](https://virtualbox.org)
+- `cd vm`
+- `vagrant up`
+- Log in with username `p4` and password `p4` and issue the command `sudo shutdown -r now`
+- When the machine reboots, you should have a graphical desktop machine with the required
+software pre-installed.
+
+To install dependencies by hand, please reference the [vm](../vm) installation scripts.
+They contain the dependencies, versions, and installation procedure.
+You can run them directly on an Ubuntu 16.04 machine:
+- `sudo ./root-bootstrap.sh`
+- `sudo ./user-bootstrap.sh`
