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.

Review the current slide show to choose an existing slide that needs a better caption, then consult the Appendix in the training manual if help is needed. Done means the selected slide has one or two added captions that improve its description.
