+            - [ ] Comment on this issue tagging Chayn staff (@kyleecodes) to be assigned this issue.
+            - [ ] If you are a Chayn volunteer, we will assign you as a reviewer to the PR after you've accepted an invite to join this repo as a collaborator.
+            - [ ] Review the pull request. Check dependency files (such as package.json) to verify that the dependency has not already been updated.
+            - [ ] See GitHub Docs below for guidance. Check the files changed, dependency review, and workflow test runs.
+            - [ ] Upgrade the dependency. Please research it instead of simply updating the version numbers, as some upgrades may require code changes.
+            - [ ] Verify tests and happy paths are functional by cloning the dependabot branch and running locally.
+            - [ ] Next, complete the pull request review if you a volunteer, or notify us in issue discussions that you are done reviewing the PR. 
+                - If the dependency upgrade does not pass tests or breaks the app, notify us in issue discussions, or in the pull request review if you're a volunteer. You may work on the required code changes or finish the review as is.
+                - If the dependency upgrade passes tests without breaking the app, notify us in the issue discussions, or approve the pull request if you are a volunteer. Then we'll get the PR merged!
