E. g.: [qlwiki url=http://de.wikipedia.org/wiki/Joomla] - of course with { instead of [.

If you use a local, private wiki (with private user access), enter the url in qlwiki tag or simply use the default settings of plugin in backend.

Every default setting can be overridden in tag itself; accessable params are:

* url - e. g.http://de.wikipedia.org/wiki/Joomla
action - e. g. 'render', I can't imagine a case*  when to set action not to render; but just in case you need it set
* title - for local wiki to get entry intended; ! replace blank space ' ' by underscore '_' !
* login - set yes for your local, private wiki if locked behind a login
* user - e. g. 'wikiuser', for local, private wiki locked behind a login
* password - e. g. 'yourPassword$!??', for local, private wiki locked behind a login
* useragent - string
* edit - e. g. 0=never; 1=always; 2 = only Super Administrators
