Provides good and simple installation instructions. At first, when I got to the last line I wondered "ok, so that was it but how do I use it?". There are no usage instruction or details of what it does except "This plugin allows you to log into Joomla and also automatically be logged into MediaWiki" and it really is that simple. The plug-in logs you in to MediaWiki, and you do not need to have an account on MediaWiki first. Also when registering at your MediaWiki site, it redirects you to your Joomla registration page.
