Execute this src block:

#+begin_src emacs-lisp :results none
(info "(org) LaTeX header and sectioning")
(describe-variable 'org-latex-classes)
#+end_src

Browse the *info* buffer and study the *Help* buffer.

Then type

`M-x customize-variable RET org-latex-classes RET`

and add your custom class or modify an existing class to your liking.

HTH,

Chuck
