Help!/Linking to categorical pages

From Tardis Wiki, the free Doctor Who reference

Hello... Recently I have been looking at the (unfortunately) neglected 'job' category of companions. While doing so, I discovered there was a page for Journalists, but not Models. (Yes, I was working on Amy's jobs) Also, there were categorical pages for both Journalists and Models. However, when I tried to add a link to the categorical pages on the journalist and model (which I created) pages, I couldn't figure out how. Has anyone done it in the past? And it so, how?
