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 to identify an existing slide that needs a caption, then consult the Appendix in the training manual for the expected format. Add one or two captions to that slide and verify that they appear correctly in the slide show.
