+## Installing Ruby and RubyGems
+
+The easiest way to install Ruby and RubyGems is via Ubuntu's built
+in package manager:
+
+{% highlight bash %}
+$ sudo apt-get install
+{% endhighlight %}
+
+You'll also want to verify that RubyGems is fully updated, since the
+packages can often get out of date:
+
+{% highlight bash %}
+$ sudo gem update --system
+{% endhighlight %}
+
+## VirtualBox OSE
+
+By default, VirtualBox installed via Ubuntu's package repositories
+will be "VirtualBox Open Source Edition (OSE)." While Vagrant will work
+fine with this edition (as long as its version 3.1 or higher), there
+are some additional configuration steps necessary within the Vagrantfile.
+VirtualBox OSE doesn't support headless VMs, so you must always boot
+into a GUI:
+
+{% highlight ruby %}
+Vagrant::Config.run do |config|
+  # Add this anywhere in your Vagrantfile
+  config.vm.boot_mode = "gui"
+end
+{% endhighlight %}
+
+<div class="info">
+  <h3>Vagrantfile?</h3>
+  <p>
+    Not sure what a Vagrantfile is? Don't worry! The getting started guide
+    will get to it. If you're not at that point in the guide yet, just put
+    this page in a background tab and remember to come back and check on it
+    when you cover Vagrantfiles.
