Short answer:

M-x load-file RET foo.el
M-x foo-mode

Long answer:

You will make things easier on yourself by putting foo.el in the system
site-lisp directory (C-h v load-path) or in any directory of your
choosing that you add to load-path (by modifying your ~/.emacs file).

You will make things run much faster if you M-x byte-compile-file foo.el
(before loading it).

foo.el will likely contain installation instructions in the comment
block near the top of the file, which will suggest autoload commands to
add to your system's default.el file or your personal .emacs file (so
you don't have to explicitly load it).

The installation instructions will also likely show you how to add an
entry to auto-mode-alist, to invoke foo-mode automatically when editing
files with that mode's conventional name.

P.S.  Please post questions to gnu.emacs.help in the future; that's
where I've directed followups to this message.

In the buffer you want to use it in, you can call it like any other
emacs command.  Like:

    M-x zachs-mode

You should also look at the Elisp docs under "Modes".  Especially read
about the variable auto-mode-alist.
