The introduction is an important part of your documentthough it should not be the most important part.
It is generally a very good to write other section except the introduction too.
You can use the following ways to write lists:
Shell commands look like ls -l. Python
snippets look like print 1.
Longer python things should be in pre
def foo():
pass
Or they can be outlined
rootscript.pyLikewise, HTML can be outlined too:
example.html
