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 slides and read the Appendix in the training manual for the expected format. Create one additional slide featuring an octocat, matching the repository's existing presentation style; done means the new slide is included and renders consistently with the others.
