It's not hard, actually. It's just not well documented (IMO).

See the Emacs manual, node `Lisp Indent'.

Personally, I think the explanation given there is inadequate, and this (or
more) should really be in the Elisp manual (you need some Lisp code to customize
indentation of various Lisp sexps) - there is nothing in the Lisp manual about
it. I've just filed a doc bug about this.

After reading that node, `grep' the Lisp source code for places where it puts
property `lisp-indent-function' on various function and macro symbols. Just copy
what's done there. See also `C-h f lisp-indent-function', which describes the
function that uses the symbol property.
