Saving A Photoshop Image, Jpeg Options

I imported this Jpeg image to PS to add text, when I go to save the image it prompts a text dialog box that says Jpeg Options. I want to save the highest quality possible but do not understand what this box is informing me or what I should do. I've been saving as it's shown, looks ok but maybe I' doing it wrong. Can anyone explain how to understand this dialog box? It would be greatly appreciated.....Jerry
