[GingerKiwi]

@sasha-go and @CBID2, Please add all six contributors on your team to the repo as "Read" access. Process:

• [x] 1. Sasha. Accept the invite to have Admin access. Chrissy, I just upgraded your access from Maintainer to Admin.

• [x] 2. Starting on the main repo page, click on the following:

• [x] Settings > Collaborators and Teams > Add People.

• [x] #14

• [x] #15

• [x] #18

Thanks!!

You two can decide if you each want to do three contributors, or do them together.
