+\begin{frame}[fragile]{Installing VirtualBox Guest Additions}
+  Many Linux distributions offer the Guest Additions in their package repositories.
+
+  We will install it using the repositories:
+
+  \begin{minted}{bash}
+  sudo -i
+  apt update
+  apt install virtualbox-guest-utils \
+    virtualbox-guest-x11
+  \end{minted}

+\begin{frame}{Installing using the ISO}
+  If you install Windows, or some other OS that does not have the Guest Additions
+  in a package repository, then they can be installed via a CD image.
+
+  \menu{Devices > Insert Guest Additions CD Image}
+
+  This will insert the Guest Additions as a virtual CD.
