-    \item In this class we will use a command-line interface, which allows the
-      user to interact with the computer by typing in commands in a ``terminal''
-      window. Computing professionals prefer to use the command line interface,
-      built into operating systems like Linux, instead of using the graphical
-      user interface. In many situations command line interface tends to be very
-      efficient and effective, for example, it allows you to complete some tasks
-      with a simple one line command instead of using the ``pumping'' motion of
-      the mouse!

-    Once your docker installation is complete, please locate a terminal window
-    on your machine. In MacOS and Linux, you can search for a ``terminal'' and
-    on Windows machines look for ``cmd'' (command prompt). If you are using
-    Windows, we recommend using a Linux-based terminal, a step that you will
-    complete when installing Git in Section 2, step 2.

-    Now in the terminal window type {\tt docker run hello-world} command and
