Add A New Slide

## We Need More Slides
Grab another octocat and create a new slide from scratch.
If you need help, check out the Appendix in the training manual.

Start by inspecting the repository’s existing slide structure and the Appendix in the training manual. Determine where slides are defined and how an octocat is used before creating the new slide. Done means the repository contains one additional octocat slide that matches the existing presentation.
