Newbie needs some help

First of all, I want to apologize... I don't think I posted to the right location in the forum. I am very new to Final Cut Pro X. Here's what I need help with.

I am filming in front of a green screen... talking about some random topic. In the background I have some random picture or video. I'm good so far putting my project together in FCPX. I got all that. What I don't know how to do/create is text that appears on the "screen" next to me with information on what I'm talking about... be it bullet points and/or graphics (not pictures).

I don't know what I need to do to get good quality text right next to me. Not a lower-third... something that takes up the entire screen. Can this be done in FCPX or do I need to use another program?

Any feedback would be greatly appreciated. Thanks again!
