How do I get Kontakt 5 to show up in Studio One 3 Artist? I have add on support installed.

I'm pretty new to this program.I've gotten previous software such as Antares Autotune to show up by simply clicking the install program, but I don't know how to get Kontakt 5 to show up in my plug ins so I can use MIDI. I've searched youtube, PreSonus, and Kontakt for any tutorial or tips that could help me coect this specific plug in but I can't find anything that helps.
