I don't know of any such documentation, but at least for relatively
simple input methods it's pretty straightforward to define them.  You
need to use quail-define-package to define the package containing the
input method and quail-define-rules to define translation rules used by
the input method; many examples (of both simple and more complicated
input methods) are in the Emacs lisp/leim/quail directory.  And you need
to use register-input-method to enable invoking the input method via
`C-\'; examples are in the lisp/leim/leim-list.el file.
