It's a simple thing to add text to the slide (double-click the placeholder and type the new text). And adding slides to the project is simple too (Insert > New Slide from). However, if you're not an instructional designer, it's likely that you're not clear on the structure of the course or that the project should include standard slides such as an overview slide and a lesson review slide. If you're not a graphic designer, adding some cool visuals to your project may be out of your comfort zone as well.
And that's where Captivate's Project Assets prove invaluable.
From the top right of the Captivate window, click Assets.
