extra : in [[:Category:Example category]]

From semantic-mediawiki.org

Hello, There is an extra : at the beginning of [[:Category:Example category]] in the sentence "Every category has its own article, which can be linked to by writing [[:Category:Example category]]." on page https://semantic-mediawiki.org/wiki/Help:Editing. Isn't this an error ? Thanks,

It looks like it is. The sentence is confusing anyway so I've just emended this.
