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 reading the Appendix in the training manual for guidance on how slides are structured. Locate the existing slide content in the repository and use its format as a reference for creating a new slide with another octocat; done means the additional slide is present and matches the project’s existing presentation.
