Add collaborators to this repo

## Comment below to be added as a collaborator

We will all be using this repository today. Even though it's public right now, you will not be able to make changes until you're given the correct permissions. We've automated this process via the GitHub API. Once you comment, we will add you as a collaborator.

You'll start to receive a lot of emails. (❗) You can slow these down immediately by clicking the **Unatch** button at the top of the page and selecting either the **Participating and @mentions** or **Ignore** option.

Comment on the issue as requested; the repository says collaborator access is automated through the GitHub API. Done means the requested collaborator permissions have been granted, after which you can make repository changes.
