After you've created your PR, expand this section for tips and additional instructions.

• do not merge is the default PR status and is automatically added to all open PRs that don't have the ready to merge label.
• Add the ready for content review label to start a review. Your PR won't be reviewed until you add this label.
• If your content reviewer requests changes, review the feedback and address accordingly as soon as possible to keep your pull request moving forward. After you address the feedback, remove the changes requested label, add the review feedback addressed label, and select the Re-request review icon next to the content reviewer's alias. If you can't add labels, add a comment with #feedback-addressed to the pull request.
• After the content review is complete, your reviewer will add the content review complete label. When the updates in this PR are ready for external customers to use, replace the do not merge label with ready to merge and the PR will be merged within 24 working hours.
• Pull requests that are inactive for more than 6 weeks will be automatically closed. Before that, you receive reminders at 2 weeks, 4 weeks, and 6 weeks. If you still need the PR, you can reopen or recreate the request.
