To be honest there really isn't much to it, just that you can create and upload your own graphic wordmark, and graphic wordmarks can only be .png files and must be 250x65 pixels or less. Also; the workmark graphic file is stored at File:Wiki-wordmark.png.

Go here and you can add a graphic wordmark: http://isaacsguidetotheuniverse.wikia.com/wiki/Special:ThemeDesigner

And you can request one here: http://logocreation.wikia.com/wiki/Logo_Creation_Wiki
