In section 9 of the fancyhdr manual:

   if “Section 2.2. First steps” is the current section, then

     \renewcommand{\sectionmark}[1]{\markright{\thesection.\ #1}}

   will give “2.2. First steps”

You've said you're frustrated, but I'm not sure your analogy helps.
Indeed, it sounds childish.

The texdoc command will pull up the manual for a package.  For
instance:

  $ texdoc fancyhdr

starts a pdf reader with the fancyhdr manual.

Compared to other code bases I've worked with, LaTeX packages are very
well documented.  If you need an introduction to LaTeX, the not so
short guide to LaTeX and Lamport's book are both excellent.
