A hyperlink can reference a URL, or another page within a Muse project. In addition, descriptive text can be specified, which should be displayed rather than the link text in output styles that supports link descriptions. The syntax is as follows.
[[link target][link description]] [[link target without description]]
Thus, the current maintainer's homepage for Muse can be found [[http://www.mwolson.org/projects/EmacsMuse.html][here]], or at [[http://www.mwolson.org/projects/EmacsMuse.html]].
