User experience with getting started

This is for new users in the command line.

In Exercise 1, you display the following info:

You can write to the console like so:

    <?php

    echo "text";

That is a bit confusing to people using the command line for the first time. Give some information on:

• creating a file using their favourite editor (maybe even list a number of editors depending on OS).
• show the directory location
• might want to create the file initially - at least for the 1st exercise
