Add a Caption To an Existing Slide

## Can you think of a better caption?
Each slide can have more than one caption. Check out the current slide show and add a caption (or two).
If you need help, check out the Appendix in the training manual.

Start by reviewing the current slide show and the Appendix in the training manual for the expected caption format and the available slides. Choose an existing slide and add one or two captions; the work is done when the caption appears in the slide show.
