## Describe the feature Add documentation for for `define-assembly-routine`. ## Describe the feature in more detail Currently there is no documentation for `define-assembly-routine` in [assemfile.lisp](src/assembly/assemfile.lisp). That basically mean you either now or have to guess how to write one based on the other assembly routines. That's not great. We should add some documentation to make it a little easier to write assembly routines.
