+            Here’s what will happen next:
+
+            1. Our GitHub bots will run to check your changes.
+               If they spot any issues you will see some error messages on this PR.
+               Don’t hesitate to ask any questions if you’re not sure what these mean!
+
+            2. In a few minutes, you’ll be able to see a preview of your changes on Vercel
+
+            3. One or more of our maintainers will take a look and may ask you to make changes.
+               We try to be responsive, but don’t worry if this takes a few days.
