How do I insert a title slide into a PowerPoint presentation?

I created a presentation without a title. Now I need a title slide. How do I insert a slide and then indicate to PowerPoint that its master slide should be the title master?

EDIT: Am running 2016 on a Mac.

Insert a new slide, then change its layout to Title Slide. Since you haven't indicated which version of PowerPoint you use or on what platform, it's difficult to give specific step-by-step instructions.
