Description

Every month, we try to get the newsletter up on the site within a week of emailing it. Currently, we're moving them over "by hand."

Steps to Update

In the code base, navigate to content > newsletters and create a new file 2024-10.jsx.
You can look at the existing newsletters as a template.

Make sure to add it to the index by following the steps in the "Newsletters" section in our README and update the content accordingly based on our email newsletter.
