Please add some help for reading documentation

Issue description

The Introduction to the command-line interface chapter includes a section instructing the user to learn more about the command by asking for its documentation. On Windows, this is cd /?. The output of this command starts with this (up to minor variations per Windows version):

C:\Users\Shai>cd /?
Displays the name of or changes the current directory.

CHDIR [/D] [drive:][path]
CHDIR [..]
CD [/D] [drive:][path]
CD [..]

  ..   Specifies that you want to change to the parent directory.

When I was going through this with a youth who has been using computers a lot (and even dabbled with some Python) but really needed this chapter -- the command line is completely new to her -- this looked very daunting. I had to explain what the square brackets mean, what the drives are, and even what's a parent directory.

I don't think everything needs to be explained here, but at least some syntax (like brackets) should be, and perhaps a reference to fuller explanations about the file-system; and most importantly, a disclaimer along the lines of "don't worry if not all seems clear now, it will become clearer as you move along".

Language

I haven't checked translations, but I believe English is the source...

Operating system

Windows is much scarier than Unix in this regard, because the Unix manuals have headings ("Name", "Synopsys", "Descriptions") which Windows help files lack.

:thinking: Can we just combine the "don't worry if not all seems clear now, it will become clearer as you move along" disclaimer with a link to preexisting more in-depth material on the topic and be done with it? A(nother) lengthy explanation might make the tutorial itself more daunting.
